A car starts from rest and accelerates at 9 m/s². After 240 m. the final speed is 66 m/s.
What is Uniformly Accelerated Motion?
Uniformly Accelerated Motion is the motion of an object where the acceleration is constant.
A car starts from rest, that is, its initial speed is 0 m/s. It accelerates at 9 m/s². We can find the final speed after 240 m using the following kinematic equation.
v² = u² + 2 × a × s
v² = (0 m/s)² + 2 × (9 m/s²) × 240 m
v = 66 m/s
where,
- v is the final speed.
- u is the initial speed.
- a is the acceleration.
- s is the displacement.
