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.
A student is on the roof of the SP building, 15.0 m above the ground. Your physics instructor, who is 163 cm tall, is walking alongside the building at a constant speed of 0.35 m/s. If you wish to drop an egg on your instructors head, where should the instructor be when you release the egg? Assume the egg is in free fall and air friction is “negligible”.
The friction force that a horizontal surface exerts on a 62 kg object is 23 N. If the initial speed of the object is 27 m/s, what distance will it slide before coming to a stop?
A skydiver is at an altitude of 1520 m. After 10.0 seconds of free fall, he opens his parachute and finds that the air resistance, FD , is given by the formula FD = −bv, where b is a constant and v is the velocity. If b = 0.750, and the mass of the skydiver is 82.0 kg, first set up differential equations for the velocity and the position, and then find: (a) the speed of the skydiver when the parachute opens, (b) the distance fallen before the parachute opens, (c) the terminal velocity after the parachute opens (find the limiting velocity), and (d) the time the skydiver is in the air after the parachute opens.
A 0.15 kg baseball is thrown horizontally (parallel to the ground) from a height of 2 m with an initial speed of 25 m/s. Neglecting viscosity and drag, what is the vertical component of speed when the ball reaches the batter's box, 18 m away from the pitcher? Use g = 10 m/s^2.
A skier moving at 4.23 m/sm/s encounters a long, rough, horizontal patch of snow having a coefficient of kinetic friction of 0.220 with her skis. How far does she travel on this patch before stopping? Suppose the rough patch in part A was only 2.93 mm long. How fast would the skier be moving when she reached the end of the patch?
You are the physics consultant working on an action movie set where an SUV must start from rest, accelerate along a pier, and jump over a stretch of water to land in a departing ferry. (The director assures you it will all be very exciting.) The drawing below shows the situation. The SUV has four-wheel drive (see problem N5D.1), and the coefficients of friction between the tires and the pier’s surface are us =3/4 and uk = 1/2. Calculate the length L (as a fraction or multiple of D) of the run along the pier that you will need for the SUV to make it to the ferry. Ignore air drag.
If a 2 kg object is initially at rest on a frictionless, horizontal surface and subjected to a 13.7 N force in the positive x-direction over a distance of 3.25 meters, what will the object’s final speed be? Assume the answer in in m/s.
A bowling ball is dropped from the top of a building that has a height of h = 112 m. Part (a) Assuming air resistance is negligible, what is the ball's speed, vf in m/s, when it strikes the ground?Part (b) If drag produces an opposing force of 10 N while the ball's falling, what is the ball's speed, vf in m/s, when it strikes the ground? Assume the ball has a mass of 5 kg.Part (c) A different ball was dropped and the final speed was measured to be vf = 8.5 m/s while the drag force was measured to be 50 Newtons. What is the mass of this ball in kg?
