Question

A car starting from rest travels 100m in 8s with uniform acceleration. Find the acceleration of the car

Answer 1

using
$s = ut + 1 \div 2at^{2}$
we get 100= 1÷2(a)(64)
32a=100
a=100/32

Answer 2

From the above given details, the car starting from the rest travel roughly about 100m.  

When it comes to the time duration, it is measured as 8 s.  

It is happened with the uniform acceleration.  

We can consider distance (d) as 100m and time (t) as 8s.

The calculation of acceleration is given below.

Acceleration a = d/t which is   100m/82.

Finally we can get the acceleration a as 12.5 m/s.
