A powerful motorcycle can produce an acceleration of 3.12 m/s\textsuperscript{2} while travelling at 84 km/h. At that speed, the forces resisting motion (e.g. friction and air drag) total 3.480E+02 N. What is the magnitude of the force that motorcycle exert backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 2.400E+02kg?

A 2.5-kg fireworks shell is fired straight
up from a mortar at an initial speed that would reach a height of 1.100E+02 m if air resistance is neglected (not a reasonable
assumption here.) If the mortar itself is a tube of 0.45 long, what is the ratio of the average force on the
shell to the shell's weight?

An elevator filled with passengers has
a mass of 1.700E+03-kg. The elevator is going up at a
constant velocity of 1.2 m/s when it begins to slow down
at a rate of 0.6$m/s^2$ for 8.5 s.What is the tension in the cable after the elevator begins to slow down?

\question
A cars bumper is designed to withstand a 4.0-km/h (1.1-m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.288-m while bringing a 1.040E+03-kg car to rest from an initial speed of 1.19-m/s.

\question
Two figure skaters are coasting in the same direction, with the leading skater moving at 5.55-m/s and the trailing skater moving at 5.91-m/s. When the trailing skater catches up with the leading skater, he picks her up without applying any horizontal forces on his skates. If the trailing skater is 50\% heavier than the 48-kg leading skater, what is their speed after he picks her up?

Two figure skaters are coasting in the same direction, with the leading skater moving at 5.71-m/s and the trailing skater moving at 5.91-m/s. When the trailing skater catches up with the leading skater, he picks her up without applying any horizontal forces on his skates. If the trailing skater is 50\% heavier than the 54-kg leading skater, what is their speed after he picks her up?
