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...

Oblique Impact: A 5-kg cannon ball is launched from a height ho = 15 m at a speed vo= 25 m/s and an angle of 30° at a target a distance dı away. It hits the bullseye which is located on a plane, as shown, 5 m above the ground. If the coefficient of restitution is e = 0.75, determine the velocity before impact, v1 , and the velocity after impact, v'1, also determine the distance the ball travels after...

Projectile Motion and Impact: Just for fun, a golfer: throws a golf ball horizontally through the air and watches it bounce again and again down a long straight concrete path. The ball is thrown horizontally from a height of h_0 = 1.5 m with an initial speed of V_0, = 28 m/s The coefficient of restitution between the golf ball and the concrete is e = 0.92. Determine the maximum vertical height the golf ball will reach after its third bounce. h_3. Determine a formula for...

The catapult shown below is used to lay siege to your neighbor's cubicle. You fire 1-g peanut M&Ms at their desk until they surrender. The catapult arm moves from horizontal to 30° in 0.1 s, when it hits the crossbar and releases the projectile. Assume air resistance is negligible and the arm velocity is constant until it hits the crossbar. If the M&M lands on their desk 3 meters away in 1s, determine: A. The velocity of the projectile as...
