Question

car travelling at 36 kilometre per hour. If its velocity increases to 72 km per hour in 5 seconds then find the acceleration of the car in SI units​

Answer 1

Answer:

2 m/s²

Explanation:

Given data :-

1. Initial Velocity - 36 kmph which is 10 m/s ( multiply 5/18 to kmph to convert it to m/s)
2. Final velocity - 20 m/s
3. Time taken - 5 sec

$accearation = \frac{v - u}{t}$

where v is final velocity

u is initial velocity

t is the time covered

applying all of this into the actual equation

$a = \frac{20 - 10}{5}$

which gives ...

a = 10/5 = 2 m/s²

Hope you had a good day
