A gymnast of mass 62.0 hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value for the acceleration of gravity. Calculate the tension in the rope if the gymnast hangs motionless on the rope. Calculate the tension in the rope if the gymnast climbs the rope at a constant rate. Calculate the tension in the rope if the gymnast climbs up the rope with an upward acceleration of magnitude 0.600 . Calculate the tension in the rope if the gymnast slides down the rope with a downward acceleration of magnitude 0.600.
Create a visual display for a tennis ball rolling horizontally along a table and as it goes off the table. Sketch and label all forces acting on the ball in as a minimum three different locations of its motion.
Boat A negotiates a curve whose radius is 363m. Boat B negotiates a curve whose radius is 110m. Each boat experiences the similar centripetal acceleration. What is the ratio of speed of boat A to that of boat B.
A 220 g block on a 50 cm long string swings in a circle on a horizontal, frictionless table at 95.0 rpm. what is the tension on the string.
A rifle with a barrel length of 56 cm fires a 14 g bullet with a horizontal speed of 350 m/s/s. The bullet strikes a block of wood and penetrates to a depth of 13 cm.
