55. A home run is hit in such a way that the baseballjust clears a wall 21 m high, located 130 m fromhome plate. The ball is hit at an angle of 35° to thehorizontal, and air resistance is negligible. Find(a) the initial speed of the ball, (b) the time it takes theball to reach the wall, and (c) the velocity componentsand the speed of the ball when it reaches the wall.

Imagine that you hit a ball at ground level and send it toward the wall with a speed at 18 m/s at an angle of 32° above the horizontal. (a) How long does it take for the ball to reach the wall if it is 3.8 m away. (b) How high is the ball when it hits the wall?
An archer shoots an arrow horizontally and his friend drops a marble from the same height when the arrow is released. In the absence of air resistance, which of the following happens? The arrow hits the ground first. The marble hits the ground first. O Both hit the ground at the same time. You cannot tell from the information given.

Use the graph below to answer the next three questions. Two projectiles are launched on a planet without an atmosphere (g is NOT 9.8 m/s). Projectile A is in motion for 6 seconds, while projectile B is in motion for 3 seconds before hitting the ground.

During a recent winter storm, bales of hay had to be dropped from an airplane to a herd of cattle below. Assume the airplane flew horizontally at an altitude of 185 m with a constant velocity of 44.0 m/s and dropped one bale of hay every 4.0 seconds. It is reasonable to assume that air resistance will be negligible for this situation. About how far apart from each other will the bales land on the ground?

2. Assume that a particle, initially at the origin, travels in space with a velocity of V = cos(at)î + (5 – 10t)f – k, where t stands for time. (a) What is the acceleration of the particle as a function of time? (b) What is the position of the particle as a function of time? (c) Which component(s) of the particle's position vector will become zero again once the particle leaves the origin?
Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. c) Find the average force exerted by the club on the ball. d) Find the average shear deformation of the club's 0.800 m long and 1.00 cm diameter steel shaft.
a) If Billy-Joe kicks a stone with a horizontal velocity of 3.50 m/s, and it lands in the water a horizontal distance of 5.40 m from where Billy-Joe is standing, what is the height of the bridge? b) If the stone had been kicked harder, how would this affect the time it would take to fall?
A ball is projected with an initial upward velocity component of 35 m/s and a horizontal component of 30 m/s. The maximum height reached by the ball is:
in a circus act, an acrobat rebounds upward from the surface of a trampoline at the exact moment that another acrobat, perched 9.0 m above him, releases a ball from rest. While still in flight, the acrobat catches the ball just as it reaches him. If he left the trampoline with a speed of 7.6 m/s, how long is he in the air before he catches the ball? (FYI I don't necessarily need the answer but I would really like to know how to solve it, as I don't know how)
