Question

A truck starting from rest travels down a hill with a constant acceleration. it travels a distance of 300 metres in 15 sec. calculate its acceleration. find the force acting on it, if it's mass is 10 metric tonnes

Answer 1

here is the solution

Answer 2

☺ Hello mate__ ❤

◾◾here is your answer...

u = 0 m/s

t = 15 s

s = 300 m

According to the second equation of motion:

s = ut + 1/2 at^2

300 = 0 + 1/2 × a × (15)^2

a = (300 × 2 )/225 = 2.66 m/s^2

10 metric tons = 10000 kg

Now,

Force = mass × acceleration

⇒ F= 10000 × 2.66 = 26600 N

I hope, this will help you.

Thank you______❤
