Question

for a body,the displacement in 10 seconds, when it aquires 4 ms^-1 in 2 seconds is

Answer 1

Answer:

Explanation:

Given, initial velocity u = 0m/s

Velocity after 2s, v = 4m/s

Acceleration a = (v - u)/t = (4-0)/2 = 2m/s^2

Under uniformly accelerated motion,

After t = 10s

S = ut + (1/2)at^2

S = 0 + (1/2) x 2 x (10^2) = 100m

S = 100m
