Question

An object moves along a straight line with an acceleration of 2m/s². if its initial speed is 10m/s ,what will be its speed after 2 secinss

Answer 1

Acceleration ( a ) = 2 m/s^2

Initial Velocity ( u ) = 10 m/s

Time ( t ) = 2 seconds.

Suppose, velocity after 2 seconds = 'v'


Now,

By Newton's First Equation =>

v = u + at

v = 10 + 2×2

v = 10 + 4

v = 14 m/s........●
