Question

A truck start from rest and rolls down a hill with a constant acceleration.it travel a distance of 400 in 20 find its acceleration find the force acting on it if it's mass is 7 tones

Answer 1

By using basics you can find the answer.

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 tons = 700kg

Now,

Force = mass × acceleration

⇒ F= 700 × 2 = 1400 N

I hope, this will help you.

Thank you______❤
