Problem 3: A ball is thrown so that it just clears a 25-ft wall that is 100 ft. away. If it left the hand 5 ft. above the ground and at an angle of 60° to the horizontal, what was the initial velocity of the ball?
A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.47 m/s at an angle of 83.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table?
A projectile is fired from the edge of a cliff, with an initial speed of 185 m/s at an angle of 40.0° above the horizontal. The projectile rises and then falls into the sea next to the cliff. The height of the cliff measured from the sea level is h. The time of flight of the projectile until it hits the water is 40.0 s. Ignore air resistance. What is the height h of the cliff? What is the maximum height the projectile has reached (measured from the seal level)? What is the magnitude of the ball's velocity just before it hits the ground?
A roofer tosses a shingle off a 240.1 m high roof, giving it an initial horizontal velocity of 10 m/s. How far from the building does the shingle land? What is the acceleration of the shingle as it leaves the roof at 2m/s^2?
You hit a golf ball from the (level) ground, with an initial speed and an initial angle. Ignore air resistance. (This is very unrealistic.) The initial speed is v0 = 23.7 m/s, and the angle the ball is hit at is θ = 46o. Calculate vx0, the initial horizontal component of velocity (in m/s). What equations describe the trajectory of the golf ball?
Chinook salmon can cover more distance in less time by periodically making jumps out of the water. Suppose a salmon swimming in still water jumps out of the water with velocity 6.03 m/s at 40.6° above the horizontal, re-enters the water a distance L upstream, and then swims the same distance L underwater in a straight, horizontal line with velocity 2.92 m/s before jumping out again. Where L=3.67 m; t1= 0.801 sec this is a time when fish are over the water; t2= 1.256 sec; Ttotal =2.057 sec; the average horizontal velocity is 3.57 m/s. Consider the interval of time necessary to travel 2L. How is this reduced by the combination of jumping and swimming compared with just swimming at the constant speed of 2.92 m/s? Express the reduction as a percentage.
A guy is standing on a relatively flat surface (h = 0 m). A pesky drone is flying overhead at a height of 120 m above the ground and with a velocity of 15 m/s. The guy gets annoyed and fires an arrow with an initial velocity of 100 m/s the instant the horizontal distance between him and the drone is 5 m. At what angle must he fire the arrow in order to hit the drone? Take the guy's height to be 1.8 m. Just to clarify, would shooting an arrow follow the same rules as a regular projectile motion problem? Thanks.
A golfer hits an approach shot with a velocity of 38.2 m/s at 50 degrees above the horizontal. The golf ball lands directly next to the hole, 5.50 m above the ball’s original position, and stops immediately. What was the TOTAL final velocity of the golf ball directly before it hit the ground?
A cannonball is shot with an initial speed of 30.0 m/s and 25.0º angle above horizontal from a height of 12.0 m. How far can the cannonball go horizontally when it lands on the ground, in meters? Use g = 10.0 m/s2. (Hint: Clearly label quantities along x- and y- components and write down all steps.)
