Given
A truck is in rest
- u = 0
- V= ?
- t=10sec
- a = 10m/s²
To find
- final velocity
- in km/h
Solution
From motion of Equation
- V=u+at
Putting the value in Equation
=>V = 0 + 10 × 10
=>V=100
For changing the value in km/h
multiply it with 18/5
100×18/5 = 360km/h
- 18/5 is short way to find any value in m/s to km/h
- and we also find km/h to m/s by 5/18
Hence,the value of final velocity is 100m/s
