A cyclist intends to cycle up a 7.8° hill whose vertical height is 150 m. Assuming they start from rest and the mass of the bicycle plus the cyclist is 75 kg (a) Calculate how many kJ of work must be done?
(b) If the cyclist instead does 120 kJ of work, what will their velocity in m/s be at the top of the hill?

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

Abody of weight 60 kg is standing in a lift the lift going upward with a uniform velocity of 4.9 metre per second slows down and stops in two seconds then apparent weight of the body during the slow down process is
