The distinction between mass and weight was discovered after Jean Richer transported pendulum clocks from Paris, France, to Cayenne, French Guiana, in 1671. He found that they quite systematically ran slower in (Cayenne than in Paris. The effect was reversed when the clocks returned to Paris. How much weight would a 90.0 kg person lose in traveling from Paris, where g = 9.809 5 m/s2, to Cayenne, where g = 9.780 8 m/s2? (We will consider how the free-fall acceleration influences the period of a pendulum in Section 15.5.)
The front 1.20 m of a 1 400-kg car is designed as a crumple zone that collapses to absorb the shock of a collision. If a car traveling 25.0 m/s stops uniformly in 1.20 m, (a) how long does the collision last, (b) what is the magnitude of the average force on the car, and (c) what is the acceleration of the car? Express the acceleration as a multiple of the acceleration of gravity.
A 5 kg box rests on a tabletop. On one side, it compresses a spring with a stiffness of 1000 N/m by 1 cm. If the friction force cancels out the force of the spring what must be the minimum coefficient of static friction between the box and table to keep the box from moving?
