cruise ship
(a) What is the ship's kinetic energy at this time?
(b) How much work is required to stop it? (Include the sign of this value.)
(c) What is the magnitude of the constant force required to stop it as it undergoes a displacement of 2.60 km?
Homework Answers
(a) kinetic energy = 0.5*6.60*107*12.62= 5.24*109j
(b) work done to stop this is exactly the amount of kinetic energy but in negative way.
so, work done = -5.24*109j
(c) F*S = W
F =5.24*109/(2.6*103) = 2.015*106N

A cruise ship with a mass of 1.1 × 107 kg strikes a pier at a speed of 0.65 m/s. It comes to rest over a distance of 5.9 m, damaging the ship, the pier, and the tugboat captain’s finances. Assume a constant acceleration occurs during the collision. Find the average force Fsp being exerted on the pier as the ship hits it, in terms of the time of interaction Δt, the initial velocity of the ship v, and the...

A tugboat tows a ship with a constant force of magnitude
F1. The increase in the ship's speed during a
10 s interval is 2.0km/h. When a second tugboat applies an
additional constant force of magnitude F2 in
the same direction, the speed increases by 12 km/h during a 10 s
interval. How do the magnitudes of F1 and
F2 compare? (Neglect the effects of water
resistance and air resistance.)
