Question

a truck starts from rest and rolls down the hill with a constant acceleration . it travels 400m in 20s. if the mass of truck is 7 metric tons, the force acting on it is​

Answer 1

ans=14, 000N

hope this helps you....

Answer 2

☺ Hello mate__ ❤

◾◾here is your answer...

u = 0 m/s

t = 20 s

s = 400 m

According to the second equation of motion:

s = ut + 1/2 at^2

400 = 0 + 1/2 × a × (20)^2

a = (400 × 2 )/400 = 2m/s^2

7 metric tons = 7000 kg

Now,

Force = mass × acceleration

⇒ F= 7000 × 2 = 14000 N

I hope, this will help you.

Thank you______❤
