Q1. A 50.0 kg crate rests on the floor. A boy pulls on a rope attached to the crate. The rope makes an angle of 60.0° to the horizontal and the boy applies a force of 25.0 newtons to the rope.
a) What is the tension in the rope?
b) Calculate the horizontal force applied to the crate. (Vector diagram required.)
c) Calculate the vertical force applied to the crate. (Vector diagram required.)
Q2. Two ropes are attached to a 200. kg sled. A 490. newton dog attached to one of the ropes applies a force of 300. N b north to the rope. A 35.0 kg dog attached to the second rope applies a force of 125 N b 36.9° south of west to the rope. Calculate the net force applied to the sled. (Vector diagram(s) required.)
a) Calculate the weight of 2.50 kg of apples.
b) Calculate the mass of 2.50 N of apples.
