A 60.0-kg and a 90.0-kg skydiver jump from an airplane at an altitude of 6.00103m , both falling in the pike position. Make some assumption on their frontal areas and calculate their terminal velocities. How long will it take for each skydiver to reach the ground (assuming the time to reach terminal velocity is small)? Assume all values are accurate to three significant digits.
Consider the 52.0-kg mountain climber shown below. (a) Find the tension in the rope and the force that the mountain climber must exert with her feet on the vertical rock face to remain stationary. Assume that the force is exerted parallel to her legs. Also, assume negligible force exerted by her arms. (b) What is the minimum coefficient of friction between her shoes and the cliff?
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 bis a constant and vis 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.
When you take off in a jet aircraft, there is a sensation of being pushed back into the seat. Explain why you move backward in the seat—is there really a force backward on you? (The same reasoning explains whiplash injuries, in which the head is apparently thrown backward.)
Suppose that the resistive force of the air on a skydiver can be approximated by f=bv2 . If the terminal velocity of a 50.0-kg skydiver is 60.0 m/s, what is the value of b?
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?
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 au airline allows a maximum of 30 kg for each suitcase a passenger brings along. (a) What is the weight in newtons of a 30-kg t1ikasr? (b) What is the weight in pounds?
What net external force is exerted on a 1100-kg artillery shell fired from a battleship if the shell is accelerated at 2.40104 m/s2? What is the magnitude of the force exerted on the ship by the artillery shell?
A bird has a mass of 26g and perches in the middle of a stretched telephone line. (a) Show that the tension in the line can be calculated using the equation T=mg2sin . Determine the tension when (b) =5 and (c) =0.5. Assume that each half of the Line is straight.
A person doing a chin-up weighs 700 N, exclusive of the arms. During the first 25.0 cm of the lift, each arm exerts an upward force of 355 N on the torso. If the upward movement starts from rest, what is the persons velocity at that point?
The force on a baseball as with a bat can be more than 8,000 lb. No human can push on a bat with that much force. What is happening in this instance?
