Russian ice skater, alina zagitova, spins her way to projected gold in the 2018 olympics. during one particular spin, she moves from a camel spin that rotates at about 95.0 rpm to a tight spin. if her rotational inertia changes from 129kgm² to 32.0kgm², what is the final spin rate of miss zagitova in rad/s and rpm

A1,700kg car is being used to give a 1,400kg car a push start by exerting a force of 140n the impulse on the smaller car during the 30.0s of contact is +670kg*m/s. what is the impulse of the smaller car on the larger car? -814 kg*m/s 0kg *m/s -670kg*m/s -550kg*m/s

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

2) the sun is wonderful source of energy. it is renewable and natural with few dangers. solar cells rely on the sun for energy. these cells would be more practical to use if they were
