The angular speed of truck wheel is increased from 900 rpm to 2460 rpm in 26 seconds. The number of revolutions by the truck engine during this time is ______. (Assuming the acceleration to be uniform).

Correct answer

0

Step-by-step solution

We know, θ = ω 1 + ω 2 2 t Let number of revolutions be N ∴ 2 π N = 2 π 900 + 2460 60 × 2 × 26 N = 728
