A tennis ball, from rest, rolls down the slope of the drawing.
At the end of the slope, the ball becomes airborne and leaves the
ground at an angle of 35 ° relative to the horizontal plane.
a) Think of the ball as a thin-walled spherical shell and figure
out how far x the ball will fly. Explain everything you do.
b) Discuss if x would increase, decrease or remain the same if the
ball was treated as a solid...

Group Activity: Ball rolling down ramp and off cliff As shown in the figure below, a hollow ball with a mass m 5.00 kg and radius r -30.0cm starts from rest and rolls a distance of 1.2 m down a 30° ramp, before reaching a flat section at the bottom of the ramp. The ball then rolls along the flat section for 1.0 m before rolling off a 2.5 m-high cliff. The ball lands a distance d from the bottom...

20) A cart rolls with negligible friction on a ramp that is inclined at an 17 degree angle above level ground. It is released from rest and reaches the bottom of the ramp in 4 seconds. How far did it travel along the ramp? a) What was the vertical height from which the cart was released? b) At the bottom of the first ramp, the cart smoothly rolls onto a second ramp without losing any significant amount of speed. The...

Projectile Motion and Motion Diagrams 3.2 A ball rolls down a long ramp to a shoot where it is released as a projectile with an initial speed of 20 m/s at an angel of 42° above horizontal and 4.0 m above the ground. See diagram. BALL RAMP GROUND A. Draw a complete motiongrantee the motion of the ball from it leaving the shoot until reaching the ground. B What is the maximum height above pre ground reached by the ball?...

h 5. A cart rolls with negligible friction down a ramp that is inclined at an 8 = 32' above level ground. It is released from rest at a height h = 52 cm. What we want to do is to figure out how fast the cart will go when it reaches the bottom of the ramp. Let's begin by establishing the equations that model the motion of the cart. Recall that we are dealing here with an example of...

Problem 2. (25 points) A golfer hits a golf ball with an initial speed of 30 m/s at an angle of 35° with the ground. The ball flies over the level ground and lands at the same height from which it was hit. a) How long does it take for the ball to reach its highest point? b) What is the range of the ball? c) Find the velocity of the ball just before it hits the ground. d) After...

A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°
A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°. (See the figure.) What is the angular speed of the cylinder about its center as it leaves the house roof? The outside wall of the house is 5 m high. How far from the edge of the roof does the cylinder hit the level ground?

In the figure, a solid cylinder
of radius 16 cm and mass 24 kg starts from rest and rolls without
slipping a distance L = 5.3 m down a roof that is inclined at angle
θ = 20°. (a) What is the angular speed of the cylinder about its
center as it leaves the roof? (b) The roof's edge is at height H =
6.9 m. How far horizontally from the roof's edge does the cylinder
hit the level ground?
