2. A child tries to flick a piece of popcorn off a table into a bowl on the floor. If the bowl is .5 cm away from the table and the table is 1.2 cm tall, what is the horizontal velocity with which the child
must flick the popcorn?

How many seconds does it take a pebble released from rest off a bridge to fall 29.4 m ? what is the pebble's speed when it has fallen 29.4 m ?

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.
