Problem 2: Peter pushed a 84 kg box down a sloping metal surface with a push force of 50 N. The slope angle o= 16°. The kinetic friction coefficient between the box and the sloping metal surface was u=0.34.
Many birds can attain very high speeds when diving. Using radar, scientists measured the altitude of a barn swallow in a vertical dive; it dropped 208 m in 3.0 s. The mass of the swallow was estimated to be 0.018 kg, and its cross-section area as 5.6 x 10-4 m2. What was the drag coefficient for this swallow as it dove?

(Enter your answer to at least three decimal places.) 0.220 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.
Two crates of fruit are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg. The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?

You are helping a friend move. Consider two boxes which have masses in factors ofm; one of mass 6m and the other of mass 7m. The coefficient of static friction betweenthe two boxes is very large. The coefficient of static friction between the boxes and thefloor is 0.7 and the coefficient of kinetic friction is 0.1. You place the large box on top ofthe small box and slide them down a 1m high ramp out of the truck. The ramp isfrictionless because it is covered with wheels. The box slides down this ramp smoothlyonto the horizontal grass with coefficient of kinetic friction is 0.142857142857143. Howfar (in meters) will the boxes slide before they stop?
David throws a 50 kg cart down a ramp with an initial speed of vi = 6 m/s. The ramp is at an angle of 20◦, and the coefficient of kinetic friction between the cart and the ramp is µk = 0.25. Additionally, the coefficient of static friction is µs = 0.55. How much time does it take to reach Ryan who is 10 m away? Assume that the cart slides and doesn’t roll.
Your Uber driver is taking you from the beach toward the esplanade tram stop because you are too exhausted to walk up the 5-degree (α=5^0) incline hill. The Uber is driving a Holden Commodore (m=1700 kg). At the base of the hill, the driver’s speed is showing v_0=20 km/h, here the driver begins to accelerate to reach the top of the gradient. The coefficient of static friction between the tyres and the asphalt is given as μ=0.13. The wind is severe on the beachfront, so you will need to consider air resistance caused by a poorly designed spoiler on the vehicle (F_air=0.8v^2). The force exerted by the motor can be considered as F_m.A. Given the acceleration of the vehicle is maximum at 1.67 m/s^2, find the analytical expression for the motor power in time.B. Assuming the maximum power output of the motor is 525 kW, how long can the vehicle maintain the acceleration (express answer in seconds, s).
