1. What is the mass in grams of an object that accelerates at a rate of 0.238 m/s2 when acted on by a force of 3.42 N?
2. What is the difference between static friction and kinetic friction? Which one tends to produce a larger force?
3. If the coefficient of static friction between the floor and a 24 kg box is 0.74, what force must be exerted to begin sliding the box?
4. What is the normal force acting on a 12 kg box resting on a 37° inclined plane?
5. A 5.0 kg object is at rest with μs = 0.2. If a force of 15 N is exerted on the box, does it move? If it does, what is the rate of acceleration of the box?
