A 50 g ball of clay traveling at speed Vo hits and sticks to a 1.0 kg block sitting at rest on a frictionless surface. What is the speed of the block after the collision? What percentage of the ball's initial energy is "lost"?
A 20.0 g ball of clay traveling east at 4.00 m/s collides and sticks together with a 50.0 g ball of clay traveling north at 6.00 m/s. What is the speed of the resulting ball of clay?
A clay ball of mass 3 kg and velocity of 16 m/s strikes a stationary ball of mass 5 kg and sticks to it... a) what was the momentum of the 3-kg ball before the collision? b) what was the momentum of the 5-kg ball before the collision? c) what was the combined omentum of the balls after the collision? d) what was the velocity of the balls after the collision? e) what is the momentum of the 3-kg ball...
A ball of clay with a mass of 0.250 kg is traveling horizontally to the left with a speed of 12.0 m/s when it hits a rod that can rotate about an axis through its center. The rotational inertia of the rod is 0.800 kg middot m^2 and the rod has a length 1.20 m. If the ball sticks to the rod, what is the angular speed of the rod and ball after the collision?
Question JO1 ball of unknown mass m is tossed straight up with initial speed v. At the moment it is released, the ball is a heighth above a spring-mounted platform, as shown in the figure. The ball rises, peaks, and falls back toward the platform, ultimately compressing the spring a maximum distance d from its relaxed position. Assume that the spring is perfectly ideal, with spring constant k, and that the mass of the spring and platform is negligible. What...
1. A ball is tossed straight up from a height of 17 meters with an initial speed of 7.2 m/s. What is its height above ground in meters after 0.869 seconds? Use g = 9.80 m/s2 . Assume 3 significant figures in your answer. 2. Suppose you release an object from rest from a height of 7.08 meters. How long does it take the object to hit the ground if g = 9.80 m/s2? Assume 3 significant digits in...
12. What is the velocity of a tennis ball just after release from a toss straight up (vertical) into the air given the following information: The ball weighs 0.7 N and was tossed with vertical force applied of 10 N for 1.2 sec.
A ball is tossed straight upwards with an initial velocity of .30.00 metres per second from a height of 20,000 meters. Assume that the only force acting on the object is acceleration due to Earth's gravity. Write out the position and velocity functions. With what velocity does the object hit the ground? When the object hits the ground, it bounces back up with one-fourth the speed that it had when it hit the ground. Determine the height of the ball...
A rock is tossed straight up from the ground with a speed of 12 m/s . When it returns, it falls into a hole 10 m deep. What is the rock's speed as it hits the bottom of the hole? How long is the rock in the air, from the instant it is released until it hits the bottom of the hole?
