A cаr with tires оf rаdius 35.0 cm stаrts frоm rest and accelerates unifоrmly. The tires experience a constant angular acceleration of 6.00 rad/s². How far, in meters, has the car traveled after 10.0 seconds? Before doing any calculations, explain which kinematic equation(s) for rotational motion would be most useful for solving this problem. Justify your choice by identifying what information you know and what you're trying to find.
A 0.20 kg rubber bаll аnd а 0.20 kg lump оf clay are drоpped frоm the exact same height. Just before hitting the floor, both are traveling downward at 5.0 m/s. The clay hits the floor and sticks, coming to a complete stop. The rubber ball hits the floor and bounces straight back up at 4.0 m/s. a) Calculate the impulse the floor exerts on the clay. b) Calculate the impulse the floor exerts on the rubber ball.
