Question

A car travels with velocity 10ms &
accelarates at 5 m/s2. Calculati final
velocity when it has travelled 30m​

Answer 1

Given= u=10m/s

a=5m/s^2

s=30m

By using 3 equation of motion

v^2-u^2=2as

v^2-10^2=2×5×30

v^2-100=300

v^2=300+100

v^2=400

v=√400

v=20m/s

Hence, the final velocity is 20m/s...

Hope this will help u.....
