1. Remember to include your data, equation, and work when solving this problem.

A 20.0 kg mass moving at a velocity of + 3.0 m/s is stopped by a constant force of 15.0 N. How many seconds must the force act on the mass to stop it?

2. Abdul is pushing his 20.0 kg little brother on a merry-go-round with a radius of 2.0 meters. If his little brother is on the edge of the merry-go-round and has an angular momentum of 360 kg m2/s, what is his speed?

Remember to identify all data (givens and unknowns), list equations used, show all your work, and include units and the proper number of significant digits to receive full credit.

    A disc-shaped merry-go-round has a mass of 100 kg and a radius of 1.60 m and is initially spinning at 20.0 rpm, with a 33-kg child sitting at its center. The child then walks out to the edge of the disc. (a) Find the initial and final moments of inertia of the system (disc + child), treating the child as a point particle. (b) State why the system’s angular momentum is conserved. (You can assume that the axis of the...

My Notes + Ask Your Teacher John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of a = 20.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 405 N is exerted at the center of the wheel, which has a radius of 15.0 cm....
