Question

A car starting from rest increases it's velocity uniformly to 15m/s in 5s. What is its acceleration?

Answer 1

ACCELERATION= CHANGE IN VELOCITY
―――――――――――――――――――–
TIME

= 15 / 5
= 3 m/s^2

Answer 2

Answer:

The acceleration is - 1.5 m/s

Explanation:

Given:-

The car moving with speed = 12 m/s

Car travelled for = 10 seconds

To find:-

Acceleration = ??

Solution:-

$acceleration \: \: \frac{(v - u)}{t}$

● U = 15 m/s

● V = 0 m/s

● T = 10 seconds

$\frac{(10 - 15)}{10}$

$\frac{ - 15}{10}$

= 1.5

Acceleration = 1.5 m/s

Therefore, the acceleration is 1.5 m/s
