Question

a mass of 500 gram is in rest how much force is required to displace it 2000 cm in 10 seconds

Answer 1

hey dear
here is your answer

given data :

initial velocity (u) = 0

displacement (s) = 2000 cm or 200 m

time taken (t) = 10 seconds

mass (m) = 500 g or 0.5 kg

to find : acceleration and force

solution :

by using 2nd eqn of motion

s = ut+1/2at^2

200 = 0+1/2*a*(10)^2

100a = 200

a = 2 m/s^2

now,

force = mass*acceleration

force = 0.5*2

force = 1 Newton

hope it helps :)
