Question

A truck starts from rest and rolls down a hill with a constant acceleration. It travels a

distance of 600 m in 10 s. Find its acceleration. Find the force acting on it if it’s mass is 7
metric tonnes. i will mark it as the brainliest

Answer 1

Answer:

The acceleration is 12 m/s squared and the force acting on the truck is 84000 Newtons.

Explanation:

$m=7 Metric Tonnes=7000kg$

$s = 600m$

$t = 10s$

$u = 0m/s$ (As it has started from rest)

$2^nd$ Equation of Motion:

$s=ut+\frac{1}{2}a{t}^2$

$600=(0*10)+\frac{1}{2}a{(10)}^2$

$600=50a$

$a=\frac{600}{50}$

$a=12m/{s}^2$

From Sir Isaac Newton's $2^nd$ Law of Motion we know that:

$F=ma$

$F=7000kg*12m/{s}^2$

$F=84000N$

Hope it helps.
