Question

A loaded truck rolls down a hilly road with a constant acceleration.The truck travels a distance of 1 km in 60 secs.What is its acceleration?Find the magnitude of net force acting on the truck if its mass is 7200 kg ?
Please give correct answer

Answer 1

here is your answer

given :

initial velocity (u) = 0

distance travelled (s) = 400 meter

time taken (t) = 20 seconds

to find : acceleration (a)

solution :

by using 2nd equation of motion

s = ut+1/2at²

400 = 0*20+1/2*a*(20)²

200a = 400

a = 2 m/s²

so, the acceleration of the rolling truck will be 2 m/s².

Answer 2

Answer:

5/9 acceleration
