Question

A truck Starts From Rest and rolls down a hill With a Constanat Acceleration Find the Force Acting on it if the Mass is 7 toons

Answer 1

Answer:

the answer is 422m......

Answer 2

Answer:

$\huge \star \underline \pink{Solution-}$

The truck starts from rest, so initial velocity = 0

Distance travelled = 400 m

Time taken = 20 s

We know the equation of motion,

$\huge\pink{S = ut + ½ at²}$

400 = 0 + ½ a * (20)2

a = 2 m/s2

Now, mass = 7 metric tonnes

= 7 * 1000

= 7000 kg

So force = mass * acceleration

F = 7000 * 2

= 14000 N
