Angular Kinematics

In the space provided simply state the answer to the following:

Calculate the angular velocity (in degrees per second) of the end of a fixed dial of radius 0.80metres if it had a linear displacement of 100metres over a time of 15seconds.

The Nature of Force

In the space provided simply state the answer to the following question:

Calculate the velocity of a ball of mass 0.05kg if its initial velocity was zero & it is hit by a bat of mass 0.7kg with an initial velocity of 50metres per second & a final velocity of 46metres per second i.e. after striking the ball.

Give your answer in metres per second

The Description of Human Movement

In the space provided simply state the answer to the following:

A ball is thrown with a velocity of 20metre per second at an angle of 30 degrees with the horizontal.

If it is caught at the same height from the ground at which it was released, neglecting air resistance:

Calculate the horizontal distance the ball travelled (answer in metres).
