Answer» Answer: 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

For a body starting from rest the displacement in 10 sec when it acquires 4m/s in 2 sec is

Answer»

Answer:

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
