Question

A truck starts from rest and roolls down a hill with constant acceleration it travel a distance of 400m ij 20sec. Find the its acceleration. Find the its the force acting on it mass is 7metric tonnes?

Answer 1

☺ 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______❤
