A Block Of Mass 5 Kg Is Moving Horizontally At Physics Question

A block of mass 5 kg is moving horizontally at a speed of 1.5 m/s. A perpendicular force of 5 N acts on it for 4 sec. What will be the distance of the block from the point where the force started acting?

Options

(a) 6 m
(b) 8 m
(c) 10 m
(d) 2 m

Correct Answer:

10 m

Explanation:

Horizontal distance,x=ut ⇒1.5 x 4 = 6m
Vertical distance,y=(1/2)at² = (1/2)(F/m)t²
Two motions are in mutually perpendicular directions. Net displacement = √(6²+8²) = √(36+64) =√100 = 10m.
