. A 55 kg student stands on a 4.6 kg surfboard moving at 2.0 m/s [E]. The student then walks with a velocity of 1.9 m/s [E] relative to the surfboard. Determine the resulting velocity of the surfboard, relative to the water. Neglect friction.
A baseball pitcher with a mass of 80 kg is initially standing at rest on extremely slippery artificial turf.He then throws a baseball with a mass of 0.14 kg with a horizontal velocity of 50 m/s. Determine there coil velocity of the pitcher.
Two stationary hockey players push each other so that they move in opposite directions. One player has a mass of 35.6 kg and a speed of 2.42 m/s. What is the mass of the other player if her speed is 3.25 m/s?Neglect friction. 7A
Consider a collision in one dimension that involves two objects of masses 4.5 kg and 6.2 kg.The larger mass is initially at rest, and the smaller mass has an initial velocity of 16 m/s [E]. The final velocity of the larger object is 10.0 m/s [E].
Calculate the final velocity of the smaller object after the collision.T/I
