An electric motor can drive grinding wheel at two different speeds. when set to high the angular speed is 2000 rpm. the wheel turns at 1000 rpm when set to low. when the switch is changed from high to low, it takes the wheel 60 sec to slow down. a) ( 5 points) what is the initial angular speed of the high setting in rad/sec b) (5 points) what is the angular acceleration in rad/s2 of the wheel? c) (5 points) what is the angular speed in rad/s 40 seconds after the setting is changed? d) (5 points) how many revolutions did it make as it changes speed?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
