A saltwater crocodile (Crocodylus porosus) with a mass of 531 kg, is seen chasing prey and reaching a speed of 25.9 km/h in 2.4 s. What is the magnitude of the work (in kJ) done by this crocodile? Enter the numerical part of your answer to three significant figures.
A 6.0 kg object is moving in the positive direction of an x axis. When it passes through x = 0, a constant force directed along the axis begins to act on it. The figure below gives its kinetic energy K versus position x as it moves from x = 0 to x= 5.0 m; Ko = 20.5 J. The force continues to act. What is v when the object moves back through x = -3.0 m? (Enter the magnitude of v.) --Select-- K (J) Ko x (m)
A farmer is using a rope and pulley to lift a bucket of water from the bottom of a well that is hy = 9.5 m deep. The farmer uses a force F1 = 59.5 N to pull the bucket of water directly upwards.

The Super Sled travels with an initial kinetic energy of 3369 J horizontally and to the right along a frictionless flat surface, initially at a height of zero (initial gravitational potential energy = 0). The driver briefly engages the rocket over a distance (Ax) of 2.000 m, pushing the sled with a force of 400.0 N over that distance. The rocket is then turned off. The sled then goes up an inclined surface with a rough surface. The coefficient of kinetic friction on the incline is uk. At the top of the incline, the sled reaches a height h = 1.500 m above the ground where the surface becomes flat and frictionless again. The sled (including the rocket and driver) has a total mass of 87.00 kg. (Notes: assume that g = 9.810 m/s² , and that the mass of fuel used by the rocket is negligible. Do not use scientific notation). After &, rocket rocket Before propulsion propulsion starts ends rough inclined surface rocket frictionless engaged coefficient of kinetic friction = H surface h = 1.500 m…
A 51.2 kg sled coasts down a hill, starting from rest. The hill is inclined at an angle of 20.8 degrees with respect to the horizontal and has a height of 7.25 m. The sled's blades have recently been greased so that the sled slides down the hill without friction. What is the final speed of the sled (in m/s) just as it reaches the bottom of the hill? Use g = 9.81 m/s2.
The speed of a block moving on a horizontal frictional surface changes from vi = 15 m/s to vf = 12.5 m/s in a distance of d = 9.5 m. How long in seconds did it take for the block to slow by this amount, assuming the acceleration is constant? If the block has a mass of 1 kg, What is the power supplied to the block by friction? What is the coefficient of kinetic friction between the block and surface μk?
A child stands on a bank beside a pond, grasps the end of a 20.0 m long rope attached to a nearby tree and swings out to drop into the water.

Ignore all frictional effects. c) Assuming the child started from rest, what angle did the rope initially make with respect to the vertical?
The figure here shows an overhead view of three horizontal forces acting on a cargo canister that was initially stationary but that now moves across a frictionless floor.
