Correct Option: C
Here's how to calculate the acceleration:
- Identify the knowns:
- Initial velocity (u) = 0 m/s (since the car starts from rest)
- Distance (s) = 40 m
- Time (t) = 10 s
- Choose the appropriate kinematic equation: We can use the equation: s = ut + (1/2)at²
- Substitute the values and solve for acceleration (a):
- 40 = (0)(10) + (1/2) * a * (10)²
- 40 = 0 + 50a
- a = 40 / 50
