here,
the tension in the string , T = 300 N
angle with horizontal , theta = 30 degree
horizontal distance , s = 10 m
the work done , W = T * s * cos(theta)
W = 300 * 10 * cos(30) J
W = 2598.1 J
Bob pulls Tallula on a toboggan with force of 300 N using a rope which makes...
Tallula is sitting on a toboggan. Bob pushes on Tallula with a force of 400 N due South. The force of friction on the toboggan is 260 N due North. The mass of Tallula and her toboggan is 65.0 kg. (a) Determine her acceleration. Give the mag- nitude and direction. (b) When Tallula has achieved a speed of 3.00 m s , Bob stops pushing. How long af- ter Bob stops pushing will Tallula come to a stop? (c) What...
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?
refer to picture.
A boy pulls his younger sister on a toboggan by a rope that makes an angle of 37.0° with the horizontal, as shown. The boy maintains a tension of 25.0 N in the rope and walks, on level ground, at a constant speed of 1.10 m/s. The combined mass of the girl and the toboggan is 30.0 kg. Determine a. the normal force exerted on the toboggan by the ground. the coefficient of kinetic friction between the...
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
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?
007 10.0 points Melvin pulls a sled across level snow with a force of 371 N along a rope that is 40° above the horizontal. If the sled moved a distance of 55.8 m, how much work did Melvin do? Answer in units of J.
a boy pulls a wagon with an 80 n directed 25 degrees above the horizontal a distance of 30 m. a) how much work does the boy do. b) how much work does he do if the force is directed parallel to the ground.
A boy pulls a 5.0-kg sled with a rope that makes a 60.0° angle with respect to the horizontal surface of a frozen pond. The boy pulls on the rope with a force of 10.0 N, and the sled moves with constant velocity. What is the coefficient of friction between the sled and the ice? A) 0.09 B) 0.10 C) 0.18 D) 0.06 E) 0.24 The answer is C 0.18, I don't undersatnd why.
