Mechanic Physics: A father racing his son has 1/3 the kinetic energy of the son, who has 1/3 the mass of the father. The father speeds up by 1.8 m/s and then has the same kinetic energy as the son. What are the original speeds of (a) the father and (b) the son?
Marble A was released at a certain height of the ramp and hit Marble B on the horizontal end of the ramp. Both Marbles A and B weighs 5 grams. The horizontal distances covered by marbles A and B after the collision are 5 cm and 35 cm, respectively. The elevation from the edge of the ramp to the ground is 15cm. Assuming that energy and momentum are conserved, what is initial potential energy (in erg; erg = dyne.cm) of Marble A? Use g=980cm/s2. Round off your answer to two decimal places. Answer correctly, thank you.
Two blocks with masses m1 = 1.4kg and m2 = 4.6kg are at rest on a frictionless surface with a compressed spring between them. When the blocks are let go, block 1 is observed to have a velocity of 4.4m/s to the left. What is the speed of block 2?
A 10-g bullet moving horizontally with a speed of 1.8 km/s strikes and passes through a 5.0-kg block initially at rest on a horizontal frictionless surface. The bullet emerges from the block with a speed of 1.0 km/s. What is the kinetic energy of the block immediately after the bullet emerges? 6.4 J 10 J 5.3 J 8.0 J 09.4J
It is a sunny day, and we have decided to do lab outside instead of staying cooped up. Ceylani goes to the top of Jordan Hall, and throws a ball of mass 4.87 kg down from the top of Jordan which is 124 m tall. Her lab partner, Tray, is waiting at the bottom to collect the ball and return it, for more data trials. The ball has a speed of 3.8 m/s when Ceylani throws it straight down. What is the speed of the ball as it reaches the ground? Your Answer: units Answer

A spring pushes against two horizontal carts that are held together by a thread on a frictionless surface. Cart A is 1.5-kg and Cart B is 4.5-kg. The thread is then burned, releasing the stored energy of the spring and the carts move away from each other. The Cart A moves with a velocity of 27cm / s to the left. What is the velocity of the Cart B, in cm / s ?
