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.
If the rocket sled starts with only onw rocket burning, what is the magnitute of its acceleration. Assume that the mass of the system is 2.50x10^3 kg, the thrust F=2.10x10^4N and the force of friction opposing the motion is known to be f=665N. a. What is the magnitude of its acceleration?
A boy coasts down a hill on a sled, reaching a level surface atthe bottom with a speed of 7.00 m/s. If the coefficient of frictionbetween the sled’s runners and the snow is 0.050 0 andthe boy and sled together weigh 600. N, how far does the sledtravel on the level surface beforecoming to rest?
A cube of mass ?? is initially at rest at thepeak of an inclined plane, which has a heightof 4.6 m and has an angle of θ = 25° withrespect to the horizontal. After it has beenreleased, you notice it to be travelingat v = 5.5 m/s as it leaves the ramp. What isthe coefficient of kinetic friction along theramp?
As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 17.0 m/s. In the process, he moves his hand through a distance of 1.45 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed.N
A 16-year-old employee working for Southern Virginia College's (SVC) bookstore during the summer months is helping prepare for Fall salesIt's a good way to make extra money, and the teen is saving for a car. Books from one supplier are shipped to the SVC bookstore in large crates equipped with rope handles on all sides. On one occasion, the teen momentarily pulled with a force of 669 N at an angle of 35.3above the horizontal to accelerate a 124-kg crate of books. The coefficient of friction between the crates and the vinyl floor is 0.588. Determine the acceleration experienced by the crate in m / (s ^ 2) Use the approximation g = 10; m / (s ^ 2)
A 400-N body starts up the incline of 30o with the horizontal (fk = 0.2) with a velocity of 3m/s. a. How long must a 500-N horizontal force act on the body to increase its velocity to 8m/s? b. How far will the body travel while the force is acting?
Recently, the Amazon and Virgin groups launched commercial space flights. These flights do not store fuel on board, instead, they inhale oxygen from the air. If the weight of one of these new rockets is 2420 kN, while a regular rocket is 19579 kN, what would be the acceleration of these two rockets close to the Earth's surface when a thrust of 25467 kN is applied?
A pitcher throws a softball toward home plate. When the ball hits the catcher's Mitt, its horizontal velocity is 32 meters/second. The softballs velocity goes to 0 meters/second in 0.8 seconds when caught. If the softball has a mass of 0.2 kilograms, what's the force of the impact? Use f= ma, where a =
In baseball, a pitcher can accelerate a 0.15-kg ball from rest to 98 mi>h in a distance of 1.7 m. (a) What isthe average force exerted on the ball during the pitch? (b) If themass of the ball is increased, is the force required of the pitcherincreased, decreased, or unchanged? Explain.
Dr. Jekyll (m = 70kg) is riding a skateboard when he realizes the cranberry juice he’s drinking is sweetened with artificial sweetener and turns into Mr. Hyde (m = 155kg). If Dr. Jekyll was initially moving at 6.5m/s, what is Mr. Hyde’s speed? (assume no external forces act)
A little toy car is powered by a CO2 cartridge that produces a thrust force according to the following function: Fthrust(t) = 6.0N e-0.2t. The car also has a friction coefficient of 0.05 due to the wheels and bearings. If the car's mass is 1.2kg, and the car travels in the +x direction, what will it's acceleration function look like as a function of time? If it starts from rest, what will vx(t) be? How fast will the car be going after 3.0s? What maximum speed will be reached by the car?
