Question

A body starting from rest travels with uniform acceleration. if it travels 100 meters in 5 seconds then what is the value of acceleration
​

Answer 1

Answer:

8 m/s square

Explanation:

Given,

Initial velocity (u) = 0

Distance travelled (s) = 100 m

Time taken (t) = 5 seconds

Find,

What is the value of acceleration.

Solution,

Using the equation of motion, s = ut + 1/2at², it can be substituted by-

100 = 0 + 1/2a ×  5× 5

100= 1/2a × 25

1/2a = 100/25

1/2a = 4

Therefore a (acceleration) = 4 × 2 = 8m/s square.
