A playground is on the flat roof of a city school, h, = 5.10 m above the street below (see figure). The vertical wall of the building is h = 6.30 m high, to form a 1.2-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of e = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. h (a) Find the speed at which the ball was launched. 18.13 m/s (b) Find the vertical distance by which the ball clears the wall. 2.1 Your response differs from the correct answer by more than 10%. Double check your calculations. m (c) Find the horizontal distance from the wall to the point on the roof where the ball lands. 2.3 Your response differs from the correct answer by more than 10%.

Note: for this problem, you can neglect air resistance.An action hero is trying to use a circus cannon to get to the roof on a building 63.8 meters away. She launches herself from the ground with an initial velocity of 29.4 m/s at an angle 59 degrees above the horizontal, but instead of landing on the roof she hits the wall of the building. launching at a speed of 47.0 m/s. She goes over the building entirely and lands on the ground on the other side.How much time does she spend in the air? What is the height of the action hero at the peak of her trajectory? How far from her launch point will she land?
A soccer ball is kicked with a speed of 9.0 m/s at an angle of 25° above the horizontal. Write the ball's velocity in terms of rectangular unit vectors, using the standard notation that î is horizontal and ĵ is vertical.
During a baseball game, a baseball is struck, at ground level, by a batter. The ball leaves the baseball bat with an initial speed v0 = 41.7 m/s at an angle theta = 40.5 degrees above the horizontal. Let the origin of the Cartesian coordinate system be the ball's position the instant it leaves the bat. Ignore air resistence throughout this problem. Enter an expression in terms of v0, theta, and g for the time it takes the ball to travel to its maximum veertical height.
Consider the frictionless water slide in the figure below. h₁ h₂ 1. If a 12.00kg dog starts from rest and slides down the water slide and has a velocity of 2.00 in the horizontal direction at point A, determine the height h₁ of the slide. m S m 2. If the bottom of the slide (point A) is 5.00m above the water level, how far horizontally does the dog travel between point A and when it reaches the water at point B? m оо B 3. How would increasing the mass of the dog impact your calculations above? It would result in the height of the slide being greater It would result in the height of the slide being less Equal Less than It would result in the dog's horizontal distance being greater It would result in the dog's horizontal distance being less It wouldn't impact any of the calculations 4. If the slide had friction, would the dog's velocity at point A be greater than, less than, or equal to the velocity without friction? Greater than
A little youngster pulls a toy block up a steep hill before releasing it at the top. He believes the block will fall in his room, but his sister believes he is attempting to fire it into her room across the corridor. Mom isn't going to be pleased if she goes down the hall and steps on the block. Assume the incline's upper end is 1.00 m (horizontally) from the boy's door, and the hallway is 1.00 m wide. Who is correct? This issue, as a whole, does not fit any of the problem types you've learnt; nevertheless, it may be divided into three individual problems. The steps below will walk you through them. There is just one evaluation required. (a) A kid pulls a 0.750 kg wooden block up an incline with an 8.43 N force that is parallel to the slope (rather than horizontal, which is more difficult). The inclination is at an angle, and the kinetic friction coefficient between the block and the incline is 0.178. Determine the acceleration of a block with a 28.0° angle and a length of 0.463 m. (c)…
An industrious chipmunk creates an acorn catapult. This acorn catapult fires a 0.00543 kg acorn at an initial speed of 21.8 m/s. The catapult can be moved to any horizontal distance from the target and it can be set to shoot the acorn at any angle between 14° and 86.6°. The chipmunk will adjust the distance and angle until he gets a shot just right, and he deems a shot to be successful when the target is hit at the moment the acorn reaches its apex d) If the acorn hits the target and bounces back, losing 24.2% of its speed in the collision, what is the magnitude of the change in the acorn's momentum from immediately before the collision to immediately after the collision? e) If the duration of the collision described in part D is 3.01 x 10^-5 s, what is the magnitude of the average force the acorn imparts onto the target?
A boy is playing flying fox over a swimming pool as illustrated in the figure. A cable mounted on the top of a tall tower runs down to the ground with an angle = 26° with respect to the horizontal. The boy at the top of the tower grabs a pulley on the cable and slides down from rest. His initial height was ho 15 m above the water. When he reaches hi above the water, he releases his hands from the pulley and falls into the water. The boy is subject to the regular force of gravity (g-9.80665 m/s2). Ignore friction and air resistance. <=10m (a) Determine the speed of the boy at the moment he releases his hands from the pulley. Answer: 9.90 m/s (b) Determine the speed of the boy at the moment he splashes into the water. Answer: 17 (c) At what angle with respect to the horizontal does the boy enter the water?

This is part of a lesson plan for the calculus class I am taking. The solution is in the textbook, but I do not understand where they came up with the answers. I am looking for a different way to solve it so I can try to understand for my test.
A space shuttle lands on a distant planet where the gravitational acceleration is 2.0 ( We do not know thelocal units of length and time , but they are consistent throughout the problem). The shuttle coasts along aleve, frictionless plane with a speed of 6.0. It then coasts up a frictionless ramp of height 5.0 and angle 0f 30°.After a brief ballistic flight, it lands a distance S from the ramp. Solve for S in local units of length. Assume theshuttle is small compared to the local length unit and that all atmospheric effects are negligible. Use x and y components.
