Question

A car starts from rest and accelerate at 9 m/s?. At the end of 240 m long drive, what is its speed.

Answer 1

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.

A car starts from rest and accelerates at 9 m/s². After 240 m. the final speed is 66 m/s.
