Two figure skaters are coasting in the same direction, with the leading skater moving at 5.5 m/s and the trailing skating moving at 6.2 m/s. When the trailing skater catches up with the leading skater, he picks her up without applying any horizontal forces on his skates. If the trailing skater is 50 heavier than the 50-kg leading skater, what is their speed after he picks her up?
A box of mass 11.6 kg is slid along the floor. The initial speed of the box is 1.8 m/s and it comes to rest after 9.2 m. What was the magnitude of the force of friction acting on the box during this motion? You must enter you answer and include the Sl units. (For example: 3.0kg) Answer: Check
A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg. If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m, how much thrust force did the rockets excert to get him to his final speed? Assume this thrust is constant over the 2.4 m.
A person with a mass of 80kg while dressed in a jump suit jumps from a plane while parachuting.They eventually reach a terminal speed of 60m/s. If you assume g = 10ms2 , = 1:21 kg m3 , what is the value of the product of constants cdA?
Somone is standing on a piece of cardboard holding a wire that is attached to a vehicle. The friction between the cardboard and road is 67N. The wire makes a 24° angle with the road. The tension on the wire is 134N. If they start from rest how long does it take them to reach a speed of 14m/s and how far have they traveled? The mass of the person and the cardboard is 80kg
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.
The net force on block A equals to 47.4 N, and the mass of block A is 14.5 kg. If at t=0 sec, the block velocity is 0 m/s, what is its velocity in unit of m/s at t=4.8 sec?
An object with a mass of 1.74 kg is initially at rest upon a horizontal, frictionless surface. An applied force of 4.11 N i acts on the object for 2.64 s. What is the object's final speed? Enter a number rounded to 2 decimal places and assume the answer has proper SI Units.
The IKAROS spacecraft, launched in 2010, was designed to test the feasibility of solar sails for spacecraft propulsion. These large, ultralight sails are pushed on by the force of light from the sun, so the spacecraft doesn’t need to carry any fuel. The force on IKAROS’s sails was measured to be 1.12 mN. If this were the only force acting on the 290 kg spacecraft, by how much would its speed increase after 6 months of flight?
A net (unbalanced) external force of 100.0 N acts on an object of mass 20.0 kg whose initial speed is 10.0 m/s. The force acts in the opposite direction from the object's motion, and it acts for 1.00 s. What is the object's final speed, in m/s?
A person steps horizontally off the roof of a single-story house that is 3.1 m high. When his feet hit theground below, he bends his knees such that his torso decelerates over a distance of 0.65 m before coming to astop. If the mass of his torso is 50 kg, what is the average net force exerted on his torso over this distance?
A student pushes a physics textbook of mass 1.15 kg across a table with a horizontal force of 5.48 Newtons. If the frictional force between the table and the textbook is 3.38 Newtons and the textbook was initially at rest, what is the speed of the textbook after 2.3 seconds? Remember to give your answer in metres per second and to at least 3 significant figures.
