Several children are on a sled pulled by a four-wheeler across a level snow-covered field. The sled is moving at a constant speed of 9.25 m/s, and the tow rope (parallel to the ground) makes an angle of 35.0°, with respect to the velocity of the sled (see the figure below). If the tension in the rope is 44.0 N, determine the work done (in J) on the sled by the tension in the rope in 14.0 s. J

Bob is pulling a box of his toys of mass 15.0 kg along a rough horizontal surface for a distance of 6.00 m. The tension force in the rope is 58.0 N and the angle is 30° with respect to the horizontal. The frictional force on the box is 12.0 N.  How much work is done on the box by the normal force, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A woman pushes a m = 2.00 kg carton a distance d = 6.40 m along the floor by a constant force of magnitude F = 16.0 N directed at an angle 0 = 26.0° below the horizontal as shown in the figure. Assume the floor is frictionless. (Enter your answers in joules.) m (a) Determine the work done on the carton by the applied force (the force on the carton exerted by the woman). J (b) Determine the work done on the carton by the normal force exerted by the floor. J (c) Determine the work done on the carton by the gravitational force. J (d) Determine the work done by the net force on the carton. J

A 246.63 kg crate slides 3.08 m until coming to a stop after being pushed by a large man. The effective coefficient of kinetic friction between the crate and the surface is 0.13. Calculate the work done by friction.

Bob is pulling a box of his toys of mass 15.0 kg along a rough horizontal surface for a distance of 6.00 m. The tension force in the rope is 58.0 N and the angle is 30° with respect to the horizontal. The frictional force on the box is 18.0 N.  How much work is done on the box by its weight force, in Joule? Use g = 10.0 m/s2.
