1. A 1.05 kg mass moves in a circle of radius 0.405 m at a speed of 5.10 m/s. Find the centripetal force in N

2. If you choose a scale of 1.0 cm = 1.3 cm/s, you would represent a velocity of 41.5 cm/s as a vector in cm long.

3. A puck goes around its circular path once every 1.42 s. Its speed is 94.7 cm/s. Find the radius of its circular path in cm.
