EXAMPLE 1: GOLF BALL STRUCK B A golf ball of mass 50 g is struck with a
club. The force exerted by the club on the
ball varies from zero, at the instant before
contact, up to some maximum value and
then back to zero when the ball leaves the
club. Assuming that thc ball travels 200 m
and the launch angle is 45°, estimate the
magnitude of the impulse caused by the
collision

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. when the carts collide, they hook together. assume that positive momentum is to the right. which graph best represents the momentum of both carts over time, before and after the collision?

How many neutrons does element x if it’s atomic number is 28 and its mass number is 87

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 = ?
