Consider a skydive r who has stepped from a helicopter and is falling through air. Before she reaches terminal speed and long before she opens her parachute, does her speed (a) increase, (b) decrease, or (c) stay constant?
A 15-kg sled is pulled across a horizontal, snow-covered surface by a force appiled to a rope at 30 degrees with the horizontal. The coefficient of kinetic friction between the sled and the snow is 0.20. (a) If the force Is 33 N, what is the horizontal acceleration of the sled?

A machine at a post office sends packages out a chute and down a ramp to be loaded into delivery vehicles. (a) Calculate the acceleration of a box heading down a 10.0slope, assuming the coefficient of friction for a parcel on waxed wood is 0.100. (b) Find the angle of the slope down which this box could move at a constant velocity. You can neglect air resistance in both parts.
A stubborn dog is being walked on a leash by its owner. At one point, the dog encounters an interesting scent at some spot on the ground and wants to explore It in detail, but the owner gets impatient and pulls on the leash with force along the leash. (a) What is the magnitude of the pulling force? (b) What angle does the leash make with the vertical?
In building a house, carpenters use nails from a large box. The box is suspended from a spring twice dining the day to measure the usage of nails. At the beginning of the day, the spring stretches 50 cm. At the end of the day, the spring stretches 30 cm. What fraction or percentages of the nails have been used?
A 20.O-g ball hangs from the roof of a freight car by a string. When the freight car begins to move, the string makes an angle of 35.0with the vertical. (a) What is the acceleration of the freight car? (b) What is the tension in the string?
Suppose you have a 120-kg wooden crate resting on a wood floor, with coefficient of static friction 0.500 between these wood surfaces. (a) What maximum force can you exert horizontally on the crate without moving it? (b) If you continue to exert this force once the crate starts to slip, what will its acceleration then be? The coefficient of sliding friction is known to be 0.300 for this situation.
A car is moving at high speed along a highway when the driver makes an emergency braking. The wheels become locked (stop rolling), and the resulting skid marks are 32.0 meters long. If the coefficient of kinetic friction between tires and road is 0.550, and the acceleration was constant during braking, how fast was the car going when the wheels became locked?
A student is attempting to move a 30-kg mini-fridge into her dorm room. During a moment of Inattention, the mini-fridge slides down a 35 degree incline at constant speed when she applies a force of 25 N acting up and parallel to the Incline. What is the coefficient of kinetic friction between the fridge and the surface of the incline?
