Agolf ball with an initial angle of 32° lands exactly 224 m down the range on a level course.

(a) neglecting air friction, what initial speed would achieve this result? [m/s]
(b) using the speed determined in item (a), find the maximum height reached by the ball. [m]

A1,700kg car is being used to give a 1,400kg car a push start by exerting a force of 140n the impulse on the smaller car during the 30.0s of contact is +670kg*m/s. what is the impulse of the smaller car on the larger car? -814 kg*m/s 0kg *m/s -670kg*m/s -550kg*m/s
