A car is traveling with uniform acceleration of 3m/s squared.if it's starting velocity was 2m/s.calculate it's velocity after it has traveled 10 m/s

Answer:

8 m/s

Explanation:

For constant or uniform acceleration, we can use kinematic equations known as SUVAT equations to model the motion. In this case, we will use the equation:

v² = u² + 2as

where

  • s is the displacement (distance and direction)
  • u is the initial velocity (speed and direction)
  • v is the final velocity (speed and direction)
  • a is the acceleration

In this case, the displacement is s = 10 m, the initial velocity is u = 2 m/s, and the acceleration is a = 3 m/s². The final velocity is:

v² = u² + 2as

v² = (2 m/s)² + 2 (3 m/s²) (10 m)

v² = 64 m²/s²

v = 8 m/s
