Question

a truck started from rest and moves down the hills with a constant acceleration it travels a distance of hundred metre in 5 second find its acceleration find the force acting on it if the mass of the truck is 5 metric ton

Answer 1

Answer:

Given:

t = 5 s

s= 100 m

m= 5 metric tons

To find:

a =?

f =?

Formulae and solutions....

s = it +1/2.at²

100 = 0+1/2× a×(5)²

100=1/2× a×25

100×2=25×a

200/25=a

a = 8 m/s²

Now,

to find the force,

F = ma

=7000×8

=56000 kg m/s OR 56000N

hope it's helpful........
