You can't.
Work = (force) x (distance) .
You can squeeze distance out of the speed, but there's no way to determine the FORCE being used.
If there's no friction and the car is traveling in a straight line, then NO force is needed to keep it going. It just keeps going. (Newton's 1st law of motion.)
Answer:
Explanation:
Initial angular velocity ω₁ = 0 , final angular velocity ω₂ = 75.9 rad /s
angle rotated = θ
= 37 x 2π
= 74 π
The formula for angular velocity
ω₂² = ω₁² + 2αθ , α is angular acceleration
75.9² = 0 + 2 α x 74 π
α = 75.9² / 2 x 74 π
= 12.396 rad / s²
