Question

A body, moving with constant acceleration, travels the distances of 4m and 10m in 1 s and 2 s, respectively. Calculate the acceleration of the body.​

• A. 2 $m/s^2$
• B. 2.5 $m/s^2$
• C. 1.5 $m/s^2$
• D. 5 $m/s^2$

Answer 1

The correct option is A 2 $m/s^2$

Newton’s 2nd equation of motion: ​
4 = u + 0.5 a ​
10 = 2u + 2a​
On solving both equations, we get,​
a = 2 $m/s^2$
