Diego pulls a 4.5 kg sled across level snow with a force, F, of 230 N on a rope that is 35.0° above the horizontal. If the sled moves a distance of 65.5 m, how much work does Diego do? what formula do i use?
A person pulls a toboggan for a distance of 35.0 m along the snow with a rope directed 25.0◦ above the horizontal. The force on the rope is 94.0 N. How much work is done on the toboggan by the pulling force?
WORK AND POWER PRACTICE PROBLEMS John pushes horizontally with an 40 N force on a 50 kg mass 20 m across a floor Calculate the amount of work lee did If this task takes 1.0 minutes, how much power was generated? The third floor of a house is 9.0 m above street level How much week is needed to move a 175 kg refrigerator from the street to the third floor? If this takes 300 0 s. how much power...
. You are using a rope to pull a sled at a constant velocity across level snow, with coefficient of kinetic friction 0.050 between sled and the snow. The sled is loaded with physics books, giving a total mass of 48 kg. (a) With what force should you pull with the rope horizontal? (b) Repeat for the rope at 30 ̊above horizontal.
A person pulls a toboggan for a distance of 28.7 m along the snow with a rope directed 20.4 ° above the snow. The tension in the rope is 97.9 N. (a) How much work is done on the toboggan by the tension force? (b) How much work is done if the same tension is directed parallel to the snow?
A person pulls a toboggan for a distance of 30.3 m along the snow with a rope directed 32.8 ° above the snow. The tension in the rope is 102 N. (a) How much work is done on the toboggan by the tension force? (b) How much work is done if the same tension is directed parallel to the snow?
A person pulls a toboggan for a distance of 40.0 m along the snow with a rope directed 20.0° above the snow. The tension in the rope is 67.0 N. (a) How much work is done on the toboggan by the tension force? _________J (b) How much work is done if the same tension is directed parallel to the snow? _________J
) child is pulled along the flat ground on snow on a sled by his father. The child and sled together have a mass of 33 kg. The father pulls the sled by a rope 40 degree angle above the horizontal. If the coefficient of friction between the snow and the sled is. 16, determine the force the father must pull with to maintain constant velocity. (you mus which is angled upward at a nd th e Normal Force and...
A dad pulls his child on a sled at a constant speed across a rugged snowy road with a force of 159 N in a direction of 42° above the horizontal. The mass of the child and sled is 38 kg. Compute the coefficient of friction. (HINT: Set up the force equations and Derive the expression the coefficient of friction between sled and snow.)
A man pulls a 10-kg sled 66 meters along an angled hill with a force of 53 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 66 meter path, during which a 102 N frictional force acts upon his sled. How much work in Joules does the man do on the sled in pulling the sled...
