Explanation Given: Initial angular velocity of wheel, ω 1 = 1.0 rev/s Initial distance of the hamster from the center, r 1 = 0.10 m Final distance of the hamster from the center, r 2 = 0.30 m Formula Used: Angular momentum is the product of moment of inertia and angular velocity. L = I ω In the absence of external torque, the angular momentum remains conserved. τ = Δ L Δ t L = constant ( If τ = 0 ) ⇒ I 1 ω 1 = I 2 ω 2 Calculation: Since there is no external torque or friction acting in the given system, the angular speed must increase when the radius decreasesand when the radius increases, the angular speed must decrease for the angular momentum to remain conserved

A skier of mass 75 kg is pulled up a slope by a motor-driven cable. (a) How much work is required to pull him 50 m up a 30° slope (assumed frictionless) at a constant speed of 2.8 m/s? KJ (b) What power (expressed in hp) must a motor have to perform this task? hp

A block of mass 1.4 kg is attached to a horizontal spring that has a force constant 900 N/m as shown in the figure below. The spring is compressed 2.0 cm and is then released from rest. a x = 0 x b (a) A constant friction force of 4.4 N retards the block's motion from the moment it is released. Using an energy approach, find the position x of the block at which its speed is a maximum. cm (b) Explore the effect of an increased friction force of 13.0 N. At what position of the block does its maximum speed occur in this situation? cm

A block of mass m = 3.00 kg situated on a rough incline at an angle of 0 = 37.0° is connected to a spring of negligible mass having a spring constant of 100 N/m (see the figure below). The pulley is frictionelss. The block is released from rest when the spring is unstretched. The block moves 11.0 cm down the incline before coming to rest. Find the coefficient of kinetic friction between block and incline. k=100 N/m Ө m
