You are about to ride a steel sled down a surface of ice with an incline of 50 degrees to the horizontal and a distance of 200 m to the bottom of the hill. Draw a free-body diagram for the instant it starts moving. What is the resulting force and acceleration the instant after it starts moving? What is the velocity at the bottom of the hill (initial velocity=0) mus of s= 0,03, mus of k= 0.015. The total mass...

1. The figure shows a box with mass m1 on a
frictionless plane inclined at angle ?1. The
box is
connected via a cord of negligible mass to another
box with mass m2 on a frictionless plane
inclined at
angle ?2 (> ?1). The pulley
is frictionless and has
negligible mass and assumes that the setup is on the
surface of the earth.
a) Provide free-body force diagram for both boxes.
b) What is the acceleration in terms of m1,...

1) Tyrion is pulling a 30 kg sled loaded with ale across an ice lake. Assume the sled starts from rest and that it moves a distance of 10 m to the right. He pulls the sled to the right with a force of 300 N at angle of 30° above the horizontal. Once again, Cersei is trying to stop Tyrion from leaving and pulls on the sled horizontally to the left with a force of 100 N. Find the...
