1.A force of 35 N is required to start a 5 kg box moving across a horizontal concrete floor.What is the coefficient of static friction between the box and the floor?
2.A helicopter accelerates upward,away from the surface of the earth,at 0.6 m/s2 while lifting a 1,375 kg car.What is the tension in the cable (ignore the cable's mass),in N,that connects the car to the helicopter?
3.An elevator is travelling upwards at a constant acceleration of 2.4 m/s2.If a 89 kg person in the elevator is standing on a bathroom scale,what would they measure as their apparent weight (in N)?
4.If you were standing 2.5 m from the centre of a circular platform which was rotating at a frequency of 19 rev/min,what would be your radial acceleration (in m/s2)?
5.Suppose that a new asteroid were discovered at a distance away from the Sun 11.4 times the distance from the Earth to the Sun.Assuming the asteroid travels in a circular orbit around the Sun,what would its orbital period be in Earth years?
