- A sled has a total mass of 57 kg and is pushed with a horizontal force from rest. It accelerates at 3.1 m/s? and moves a distance of 93 m on a horizontal surface. The coefficient of kinetic friction between the sled and surface is 0.28. Find the work done by the pushing force. Round your final answer to a whole number.A helicopter lifts a 85 kg astronaut 13 m vertically from the ocean by means of a cable. The acceleration of the astronaut is g/10. How much work is done on the astronaut by (a) the force from the helicopter and (b) the gravitational force on her? Just before she reaches the helicopter, what are her (c) kinetic energy and (d) speed?A child on a sled is initially at rest on an icy horizontal surface. The sled is pushed until it reaches a final velocity of 6.05 m/s in a distance of 15.6 m. The coefficient of friction between the ice and runners of the sled is 0.200, and the weight of the child and the sled is 375 N. Find the work done by the force pushing the sled.
- A 65.70 kg baseball player begins his slide into second base when moving at a speed of 6.090 m/s. The coefficient of friction between his clothes and the earth is 0.7480. How much work (in Joules) is done on the runner as he slides to a stop?A 5-kg block slides a distance d = 6 m down a rough incline as in the figure with 0 = 49° and v₁ = 0.71 m/s, reaching a final speed of v2 = 2.03 m/s. How much work was done by friction on the block during the slide? m 01 d W = m 0 _J 02A man pulls a 4.6-kg sled 50 meters along an angled hill with a force of 36 N, which elevates the man 28 meters above the bottom of the hill. The man then hops on his sled and slides from rest to the bottom of the hill back along his 50 meter path, during which a 299 N frictional force acts upon his sled. How much work in Joules does the man do against friction in pulling the sled up the hill?
- The graph (attached) shows the x component of a force that acts on an object that moves on the x axis. The vertical spacing between adjacent grid lines is 2.75 N, while the horizontal spacing between adjacent grid lines is 1.0 m. What is the work done by the force, in joules, as the object moves from x=1m to x=8m?A 4.5-kg block slides down a frictionless incline making an angle of 55.0° with the horizontal. (a) What is the total work done on the block when the block slides 1.4 m (measured along the incline)? (b) What is the speed of the block after it has slid 1.2 m if it starts from rest? m/s (c) What is its speed after 1.2 m if it starts with an initial speed of 1.6 m/s? m/s You can use the definition of work as the scalar product of a constant force and displacement to find the work done by each force acting on the block. Then use the work- kinetic energy theorem the find the speed of the block at any given location and for any initial kinetic energy it may have.A bicyclist starting from rest applies a force of F = 239 N to ride his bicycle across flat ground for a distance of d = 210 m before encountering a hill making an angle of θ = 17 degrees with respect to the horizontal. The bicycle and rider have a mass of m = 120 kg combined. In this problem, you can ignore air resistance and other losses due to friction.How much work, W in joules, did the rider do before reaching the hill? What is the bicycle's speed, v in m/s, just before the hill? If the cyclist starts coasting at the bottom of the hill, what distance, di in meters, does the bike travel up the incline?
- A cat's crinkle ball toy of mass 28 g is thrown straight up with an initial speed of 5 m/s. Assume in this problem that air drag is negligible. (a) What is the kinetic energy of the ball (in J) as it leaves the hand? (b) How much work is done (in J) by the gravitational force during the ball's rise to its peak? (c) What is the change in the gravitational potential energy of the ball (in J) during the rise to its peak? (d) If the gravitational potential energy is taken to be zero at the point where it leaves your hand, what is the gravitational potential energy (in J) when it reaches the maximum height? (e) If the gravitational potential energy is taken to be zero at the maximum height the ball reaches, what would the gravitational potential energy (in J) be when it leaves the hand? (f) What is the maximum height the ball reaches (in m)? mA father pulls his young daughter on a sled with a constant velocity on a level surface through a distance of 10 meters. If the total mass of the sled and girl is 35 kg and the coefficient of friction between the sled runners and the snow is 0.2, how much work does the father do?A 10 kg barbell is rolling down a hill. There is no friction or air resistance acting on it, only the force of gravity. If it starts out moving 2 ms1, and ends up moving 7 ms1, then how much work does gravity do on it?
