Activity (Free- Falling bodies 1. A. ball is thrown vertically downward From the top of a building Leaving the throwers hand with a velocity of 10 m/ sec. G ) what will be its velocity after falling 2Seconds BY How far will it fall in 2 seconds? ") What will be its velocity after Falling 10 m ?Activity (Rotational Motion ) 1 . God Compute the angular velocity in rad/s, of the crankshaft of an engine that is rotating at 4800 rpm. 2. An electric motor is turned off, its angular velocity decreases viting uniformly from woo nom to 400 rom in 5 seconds . C a Find the angular accelaration .' C and the humber of revolution C made by the motor in this 5- scond c Interval B) How many more sclouds required for the motor to come to rest? o
