(Uniform Circular Motion Question - High School Physics): A jet flies at a height of 10000 m above the surface of the Earth in a circular path around the planet. If the velocity of the jet is 150 m/s, how long does it take the jet to go around the world?
How much work is done on a 5 kg block if it is to be moved on a ramp 30° above the horizontal and height of 1 meter? What are the values of work done by each force?
1- How much work is done by the horizontal force Fp = 150N on the 18-kg block when the force pushes the block 5.0 m up along the 32° frictionless incline? (b) How much work is done by the gravitational force on the block during this displacement? (c) How much work is done by the normal force? (d) What is the speed of the block (assume that it is zero initially) after this displacement? [Hint: Work-energy involves net work done.]...
1a) How much work is required for a 60 kg person to climb the stairs near the entrance of Science 2 from the first floor to the second floor? The incline angle of the stairs is 30°, and the total height is 3.5 m. b) Suppose the same person decides to take the steeper staircase (incline ~ 35°) in the corner of the building instead. Would the work necessary to ascend to the second floor be greater, smaller, or the...
