Spectators watch a bicycle stunt rider travel off the end of a60.0° ramp, rise to the top of his trajectory and, at that instant,suddenly push his bike away from him so that he falls verticallystraight down, reaching the ground 0.550 s later. Howfar from the rider does the bicycle land if the rider has massM = 72.0 kg and the bike has mass m = 12.0 kg? Neglect airresistance and assume the ground is level.

Kramer goes bowling and decides to employ the force of gravity to "pick up a spare." He rolls the 6.50 kg bowling ball very slowly so that it comes to rest a center-to-center distance of 0.245 m from the one remaining 2.00 kg bowling pin. Treat both the ball and the pin as point objects, and determine the magnitude of the force of gravity ?⃗ grav between them.

A trebuchet is a mighty siege engine capable of flinging 90-kg projectiles a distance of 300 meters. Assuming a perfect launch angle of 45o, calculate the speed with which one of these projectiles leaves the trebuchet. You can assume the projectile lands at the same height from which it was launched.
The football player in the picture kicks the 1.5-lb ball with a velocity vA of 50 mph, as shown. The ball bounces off the turf, having a coefficient of restitution with the ball of 0.35, before landing a second time in mud, getting stuck there. Based on this: a) What will the rebound velocity, v’B, and angle be? b) How much less high will the ball bounce than it reached during the initial kick? c) What total distance will the ball travel?

In a home laundry dryer, a cylindrical tub containing wetclothes is rotated steadily about a horizontal axis, as shown inFigure P7.61. So that the clothes will dry uniformly, they aremade to tumble. The rate of rotation of the smooth-walled tubis chosen so that a small piece of cloth will lose contact withthe tub when the cloth is at an angle of θ = 68.0° above thehorizontal. If the radius of the tub is r = 0.330 m, what rate ofrevolution is needed in revolutions per second?
In the figure provided, a 266 kg crate is released from rest and hits the ground 0.600 m below after 6.42 s. What is the mass of the crate to the left of the pulley? Assume the rope and pulley are massless.
The acceleration due to gravity on one of Saturn's moons Titan (the best moon in the solar system), is 1.40 m/s?, what is the range of a projectile with a mass of 0.965 kg launched at at 16.5 m/s at an angle of 45° if you neglect air resistance (Titan actually has a thick atmosphere)?
When a basketball player takes a standing shot, a coordinate system Oxy is formed with the center of the ball as the origin (see figure). Denoting the center coordinate of the basket as (x, y), the shot's height as H₁, and the ball's speed as vo, prove that the shot angle a must satisfy the subsequent relationship to make a shot: tan α = v² gx 1 + 1 - (+2) 2g v² y то H₁ H₂
