You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of <3,0, 0> m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15...

A heavy sled is being pulled by two people as shown in the figure. The coefficient of static friction between the sled and the ground is mu_s = 0.611, and the kinetic friction coefficient is mu_k = 0.435. The combined mass of the sled and its load is m = 276 kg. The ropes are separated by an angle phi = 26 degree, and they make an angle theta = 31.4 degree with the horizontal. Assuming both ropes pull equally...

1.) A ball with mass 5.0 kg is launched upwards towards the east into the air with a speed of 15. m/s at an angle of 30 degrees to the ground. Note: For this question the motion is fully three-dimensional. Orient your axes so that the positive y-axis points north, the positive X-axis points east, and the positive z-axis points upwards (towards the sky. 1A.) If a gusting...

5. An adult uses a rope to pull a child on a sled across some ice. The sled has a mass of 5 kg. the child has a mass of 35 kg, and the adult has a mass of 60 kg. The sled moves with a constant velocity of 2.5 m/s. The rope makes an angle of 300 with the horizontal. The tension in the rope is 50 N. Find the coefficient of friction between the ice and the sled.
