Let's say your can has covers a distance of 3 m in 5 seconds under constant acceleration. Use kinematics equations and Newton's second law to calculate:
a) the acceleration of the can,
b) the net force on the can,
c) the work required to apply this force over the given distance, and
d) the power required to do this work over the given time. Use a can mass of 500 g.
a 12.0 kg mass lies at x=-80.0 cm. A 21.0 kg mass is at x= 70.0 cm. The 12.0 kg mass is not moved to a different point on the x-axis. There is not a zero net force on the 10.0 kg mass. What is the new location of the 12.0 kg mass
