A water-skier is being pulled by a tow rope attached to a boat. As the driver pushes the throttle forward, the skier accelerates. A 61.3-kg water-skier has an initial speed of 5.5 m/s. Later, the speed increases to 11.3 m/s. Determine the work done by the net external force acting on the skier.
3. Two blocks are tied together with a rope R of mass M. Block B is pushed to the right with a constant horizontal force Fa. Assume that there is no friction, and that the blocks and the rope are already in motion when we start our observations. For simplicity, let's ignore the a) Describe in general terms the motion of the two blocks connected by the rope Rope has mass M FB Note: In lecture we introduced tension in...
44. A water skier with a mass of 65 kg is pulled behind a boat that is moving with a constant speed of 25 m/s. The tension in the horizontal rope is 1.2 X 10N [S]. Calculate the magnitude and direction of the force that the water exerts on the skier's ski. (2.3) A 45. A hockey stick is in contact with a puck for 0.011 s. The speed of the puck when it leaves the stick is 32 m/s....
In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. A rider is towed at a constant speed by a rope that is at an angle of 17 ∘ from horizontal. The tension in the rope is 1500 N. The force of the sail on the rider is 30∘ from horizontal.

The masses of the boxes are indicated in each figure. Will the tension in rope A on the left be a greater than. (b) less than, (e) equal, or (dl) indeterminate compared to the tension in rupe B on the right?

In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. A rider is towed at a constant speed by a rope that is at an angle of 15 degrees from horizontal. The tension in the rope is 1900 NN. The force of the sail on the rider is 30 degrees from horizontal. What is the weight of the rider?

A sled is being pulled across rough snow by a rope at an angle of 20° to the horizontal. The sled has a mass of 31 kg and the passenger has a mass of 22 kg. The sled is moving at a steady 0.63 m/s. The force on the rope is 65 N. A. Draw a free body diagram for the sled and passenger as one thing. B. What is the normal force on the sled? C. What is the...
Please show work! A pulley of negligible mass is attached to a block weighing 504 N. A person uses the rope and pulley system illustrated in the figure to lift the block at a constant velocity. The pulleys and rope are all ideal. F_G=____________ ? A. Draw the free body diagram for the block. (Observe that three are two rope segments pulling on the block.) B. Apply Newton's first law and determine the tension in the rope, and thus, the...
Problem 4 A child is dragging a 2kg sled through a flat patch of snow (coefficient of kinetic friction: 0.1) with a constant force, by pulling on a rope at an angle of 25° to the horizontal. The sled is moving at a constant speed. (a) Draw a free body diagram for the sled as it is being pulled. (b) Find the magnitude of all the forces acting on the sled. (c) If the child were to suddenly release the...
