A ball is struck from a height (1.80 m) with an initial velocity of 12.0 m/s at an angle of 42.0° above the horizontal. The ball passes through the center of a hoop before returning to the ground which is 1.80 m below the starting point. If the ball is moving horizontally when it goes through the hoop, (hint: make sure you know the condition of equations you want to use.) use g=9.81m/s² 1. how long does it take to reach the hoop? 2. And how high above the ground is the center of the hoop? 3. How far is the ball measured horizontally from the person to where it landed? 40.0° 2.00 m
I. If s’(t) = v(t), and s’’(t) = a(t), use the fact that integration reverses differentiation (+C) and the given information about s(t) to find the particular solution to the following problem. If a model rocket’s velocity is given by a(t)= -32 m/s2 and v(0)= 10 and position at 1 second is 1,000 m, find s(t). Hint: Integrate a(t) to find v(t), then integratev(t) to find s(t), finding each C using the given info.

A projectile is fired horizontally to the west at a velocity of 21 m/s.
As part of an obstacle course, an athlete must kick a soccer ball into a 1 meter wide and 10 meter deep pit such that the ball hits a target at the bottom of the pit. In practice, a dynamics student that is participating in the race kicks the soccer ball such that the soccer ball will bounce off the far wall of the pit 5 meters below the surface and head towards the target. If the velocity of the ball before striking the wall at point at point A is v4 = 2.6i – 10j m, determine the t-component of the ) after striking the wall. The size of the ball and the target ball velocity vector (in are negligible relative to the dimensions of the pit, the gravity acceleration must be considered as g 10 m and the coefficient of restitution at point A is e =0.35. 5 m t 10 m 1m 三

A bullet is fired at an initial velocity of 150 m/s horizontally (0 degrees) at the top of a 125 m tall building. Neglecting air resistance, determine the time in seconds for the bullet to hit the ground. Use the value of the gravity in 2 decimal place. Use up to 4 decimal places. NOTE: Do not assume that this is the same problem as the previous question. The numerical values for each question are different.

Express the initial and final velocities of the ball in Cartesian vector form b. Magnitude and direction of the average force exerted on the soccer ball by the player's head in Cartesian vector form.
You are investigating an accident that occurred early on a foggy morning in Oxfordshire. A 2015 Prius Hatchback traveling due north collided in a highway intersection with a 2012 Nissan Pathfinder that was traveling due east. After the collision, the wreckage of the two vehicles was locked together and skidded across the level ground until it struck a tree. You measure that the tree is 11 m from the point of impact. The line from the point of impact to the tree is in a direction 39° north of east. From experience, you estimate that the coefficient of kinetic friction between the ground and the wreckage is 0.45. Shortly before the collision, a police officer with a laser speed gun measured the speed of the Prius to be 80 km/h and, according to a witness, the Prius driver made no attempt to slow down. Four people with a total mass of 230 kg were in the Nissan. The only person in the Prius was the 80 kg driver. The Nissan with its passengers had a mass of 2362 kg, and the Prius with its…
