PRACTICE ANOTHERA rabbit is hopping along at an approximately constant speed of 4.2 m/s. The rabbit passes a crouched cat ready to chase the rabbit. The cat takes off the instant the rabbit passes the cat, accelerating at 0.5m/s2.How long does it take the cat to catch the rabbit

What is meant by the statement" the melting poin of glycerine is 13 degree celsius

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
