s = 100 m
uk=0.2
theta = 30 degrees
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 man pulls a sled loaded with salmon. The sled and salmon have a mass of 50 kg, and the man exerts a force of 120 N on the sled by pulling on the rope. The sled moves 5 m and and μk=0.2. Find: a)The final velocity if theta=0° b)The final velocity if theta=30°
A sled with mass 30 kg slides 40 m down a hill angled at 20 degrees to the horizontal. The coefficient of friction between the sled and the ground is 0.2. a) How much work does gravity do on the sled? b) How much work does the normal force do on the sled? c) How much work does friction do on the sled? d) What is the net work done on the sled e) if the sled begins at rest...
How much power would be delivered by pulling a 10.0 kg sled along a flat,snowy field at a constant speed of 1.96 m/s with a rope at an angle of 30.0°, if μk between sled and snow is 0.30?
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...
28. How much work is done by the boy pulling his sister 30.0 m in a wagon as shown below? Assume no friction acts on the wagon 30% d (30 m)
Determine the work done by you in the following situations. A) Pulling horizontally with a force of 20 N on a 100 N sled. Sled moves 2 m at a constant velocity. (include units with answer) B) Pulling horizontally with a force of 40 N on a 100 N sled. Sled moves 2 m at a constant acceleration. (include units with answer) C) Pushing at 30° from horizontal with a force of 40 N on a 100 N sled. Sled...
Airflow lifts a 3.6 kg bird 50 m up. a) How much work was done by the flow? b) How much did its gravitational potential energy increase? A bird flies at a speed of 2.3 m/s if it has 14 J of kinetic energy. What is its mass?
given answer is 300j 18. Stella (M = 60 kg) is standing next to a sled of mass m = 40 kg on an icy surface. She pushes the sled at 3.0 m/s and bounces in the opposite direction. How much work is done by Stella during the process?
A 5-kg sled is sliding on a horizontal rough surface with a speed of 18 m/s. The coefficier kinetic friction between the block and surface is 0.15. After travelling 25-m, it encounters as covered hill (where friction can be ignored) and slides uphill. The hill makes an angle of 38。 horizontal. (a) How much work is done against friction during the 25-m horizontal travel? the maximum elevation on the hill the block reaches? (c) How much work is done against...
