B. A force act for a 0.1s on a body of mass 1.2 Kg initially at rest. The force thenceases to act and the body moves through 2m in the next ls. Find the magnitudeof force.​

Answer»

Answer:

u = 0m/s

t = 0.1s

s = 2m

Now, s = UT + 1/2at²

2 = 1/2a(0.1)²

4 = 0.01a

a = 400m/s²

Now, m = 1.2kg

F = ma

F = 1.2 x 400

F = 480N

Hope it HELPS you!!
