Kinematics of Linear Motion

An apple is thrown horizontally from the edge of a table with an initial

velocity of 2.5 m s-1. If the height of the table is 1.5 m, calculate the time

taken for the apple to reach the floor.

• 0.25

• 0.55 s

• 0.12s

• 0.86s

Determine the speed of the apple when it hits the floor.

• 3.5 ms^-1

• 0ms^-1

• 5.9 ms^-1

• 5.4ms^-1

A 4.00 kg mass is moving in a circular path of radius 4.10 m with a constant

angular velocity of 5.00 rad s-1. The centripetal force on the mass is

• 205 N

• 410 N

• 82 N

• 103 N

   A bus is moving with an initial speed u begins to slow down at a uniform rate of 3ms^-1 . calculate u if it takes 6.67s to travel at distance of 67.0m

• 15 ms^-1

• 26 ms^-1

• 30 ms^-1

• 20 ms^-1

A man is standing in a lift that is moving down to third floor of a building with constant velocity. The normal force experienced by the man is

• weightless

• less than his weight

• same as his weight

• more than his weight
