A student is standing on a 2.3 kg stationary skateboard. If the student jumps at a velocity of 0.37 m/s [forward], then the velocity of the skateboard becomes 8.9 m/s [backwards) How much is the mass of the student? (5 marks 2.
A 65 kg skater runs at 5 m/s and jumps onto his 2.5 kg skateboard which was initially stationary. What is the velocity of the skater and the board after he lands?
A 7,500-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 7 m/s. Compute how much kinetic energy was "lost" in this inelastic collision.
A 1.0-kg ball with a speed of 3.0 m/s strikes a 2.0-kg stationary ball. The collision is completely inelastic. (a) Calculate the speed of the balls after collision. (b) Calculate the total kinetic energy change during the collision
A 3.90 g bullet moving at 300 m/s enters and stops in an initially stationary 2.80 kg wooden block on a horizontal frictionless surface. What's the speed of the bullet/ block combination? What fraction of the bullet's kinetic energy was lost in this perfectly inelastic collision? How much work was done in stopping the bullet? If the bullet penetrated 5.00 cm into the wood, what was the average stopping force?
HELP ASAP 1500kg car moving at 16 m/s suddenly collides with a stationary car of mass 1000 kg Problem3 1500-kg car moving at 16.00 m/s suddenly collides with a stationary car of mass 1000 kg a) What is the total initial momentum? b) If the two vehicles lock together, what is their combined velocity immediately after the collision? c)What is change in momentum? d)What is the impulse? e) What is the average force acting on the stationary car by the...
A dog (mass 20kg) is running at 8 m/s toward a stationary skateboard (mass 2kg). When the dog reaches the skateboard, it jumps on. The dog and skateboard forward together without friction until they reach a ramp (30 degrees above horizontal). If the coefficient of kinetic friction between the ramp and the skateboard is 0.3, what is the maximum height the skateboard can reach?
Problems: 32 Points Total A 55.0-kg person, running horizontally with a velocity of 6.0 m/s, jumps onto a 9.0-kg sled that is initially at rest 17. Ignoring the effects of friction during the collision, find the velocity of the sled and person after the collision A) 1.7m's B) 2.3 m/s C) 3.1 m/s? D) 4.9 m/s E) 5.2 m/s F) 6.3 m/s 18. The sled and person coast 35.8 mon level snow before coming to rest. Use the work energy...
Mass m = 0,1 kg moves to the right with speed v = 0.39 m/s and collides with an equal mass initially at rest. After this inelastic collision the system retains a fraction = 0.63 of its original kinetic energy. What is the speed VR (in m/s) of the mass which was originally at rest before the collision?
1. A 25 kg child runs at a speed of 5.0 m/s and jumps onto a stationary shopping cart and holds on for dear life. The cart has mass 12 kg. Assuming the child rides on the cart after the collision, find the speed of the child and shopping cart just after the child jumps on. Show all work please
