A 1.25kg hockey puck (puck A) slides across a frictionless sheet of ice and collides with a puck of unknown mass (puck B) head on. The collision is completely elastic, which means no kinetic enegy is lost in the collision. After the collision, puck A moves in the opposite direction at half of its initial speed. Find the mass of puck B.
5. A hockey puck with an initial speed of 5.40 m/s slides up a frictionless ramp at an angle of 22.0 What is the distance it travels along the ramp?
A block is projected up a frictionless inclined plane with initial speed v0 = 5.05 m/s. The angle of incline is θ = 30.9°. (a) How far up the plane does it go? (b) How long does it take to get there? (c) What is its speed when it gets back to the bottom?
1. A student kicks a stone horizontally over the edge of a cliff with an initial velocity of 20.3m/s. The cliff is 43.9m above a beach. (a) How far did the stone travel in the horizontal direction? (b) What was the time of flight of the stone? (c) What is the magnitude of the final velocity just before impact with the beach? (d) What is the angle of impact below the horizon measured in degrees? 2.A plane is flying at...
Problem 4 A block of mass m slides at velocity vo across a horizontal frictionless surface toward a large curved movable ramp n and has a smooth circular frictionless face up which the block can easily slide. When the block slides up the ramp, it momentarily reaches a maximum height a shown in Figure II, and then slides back down the frictionless surface as shown in Figure III. face to the horizontal (a) Find the velocity of the ramp at...
A 5.0-kg block slides from an initial speed of 8.0 m/s to a final speed of zero. It travels 12 m down a plane inclined at 15: with the horizontal. Determine the entropy change of the block-inclined plane-Earth system for this process if originally the block and the inclined plane were at 27 degree C. Why did the block stop?
A block of ice slides along a frictionless horizontal track with a speed of 1.2 m/s. At the end of the track is a horizontally mounted spring. The ice block slides along the track until it makes contact with the spring causing it to compress. What is the speed of the ice block when the spring has been compressed by 60% of the maximum compression length?
A mass of 1 kg and initial speed 10 m/s slides across a horizontal frictionless surface and hits a spring of force constant 200 N/m. How much will the spring be compressed from its relaxed length when the block will be at rest momentarily?
a). Suppose a hockey puck slides down a frictionless ramp with an acceleration of 4.00 m/s2. What angle does the ramp make with respect to the horizontal? ____ degree b).If the ramp has a length of 5.80 m, how long does it take the puck to reach the bottom? _____ s c). Now suppose the mass of the puck is doubled. What's the puck's new acceleration down the ramp? _____ m/s^2
A skier of mass m started at rest and slides down over a frictionless inclined plane. He reached the bottom at a speed of 20 m/s. Then reached the second inclined plan. If the second inclined plane has a friction coefficient of 0.2 and inclined at angle of 20°. How far does he slide on it before coming momentarily to rest? hi =? 20°
