Question

Truck starts from rest and rolls down the hell with constant acceleration it travels a distance of 400m 20 seconds find its acceleration

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

initial velocity = 0

distance = 400m

time = 20second

s = ut + 1/2 at²

400 = 0 + 1/2 × a × 400

400 = 200a

a = 2m/s²

Hence acceleration is 2m/s²
