Answer:
Given -
- Initial Velocity, u = 114 m/s
- Final velocity, v = 77 m/s.
- Time taken, t = 9 sec.
To find -
Solution -
Here, using the equation of motion v = u + at we can find the acceleration easily.
★ Here,
- V = Final velocity
- U = Initial Velocity
- A = Acceleration
- T = Time.
Substituting the values -
→ 77 = 114 + a(9)
→ 9a = 114 - 77
→ 9a = 37
→ a = 37/9
→ a = 4.1 m/s
Therefore, the acceleration of the car will be 4.1 m/s.
