The angular velocity of the engine (and hence of the wheel) of a scooter is proportional to the petrol input per second.

One watt is the power of an agent which does work at the rate of 1J s–1  1 kilowatt = 1000 J s–1  Total Power = 150 × 500 = 7.5 ×...

(d) > 500N for time Δt1 and Δt3 and 500N for Δt2. Explanation:  During the constant velocity for time Δt2 there is no relative movement between the man and the seat and only force applied by the seat on...

(a) on the rear wheels is in the forward direction (b) on the front wheels is in the backward direction (c) on the rear wheels has a larger magnitude than the Explanation:  When accelerating the torque...

ω0 = 0 ; ρ = 100 rev/s ; ω = 2 ; ρ = 200 π rad/s ω = ω0 = αt ω = αt α= (200 π)/4 = 50 π rad /s2 or 25 rev/s2 θ = ω0t + 1/2...

θ = 100 π; t = 5 sec θ = 1/2 αt2 = 100 π = 1/2 α 25 α = 8π × 5 = 40 π rad/s = 20 rev/s α = 8π rad/s2 = 4 rev/s2 ω = 40π rad/s2...

α= 1 rad/s2, ω0 = 5 rad/s; ω = 15 rad/s w = w0 + αt  t = (ω – ω0)/α = (15 – 5)/1 = 10 sec Also, θ = ω0t + 1/2 αt2 = 5 ×10...

 The correct answer is: (a), (c) (a), kinetic  (c) mechanical

The correct answer is all  (a) kinetic  (b) total  (c) mechanical  (d) internal.

(a) on the rear wheels is in the forward direction (b) on the front wheels is in the backward direction (c) on the rear wheels has a larger magnitude than the Explanation:  When accelerating the...

(c) Statement 1 and 3 contradict each-other, hence both statements cannot be true together. But there are a situation where in both statements are false that is if some of...
