Question

A body moves along a straight path from rest with uniform acceleration 4 m/s2

. After what time

interval its velocity will be 40m/s

(A) 20 sec (B) 10 sec

(C) 15 sec (D) 16 sec
with full process​

Answer 1

Given,

u = 0 m/s

v = 40 m/s

a = 4 m/s²

To find ‘t’, use v = u + at

40 = 0 + (4)t

t = 10 sec
