A gymnast of mass 52.0kg 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 9.81m/s2 for the acceleration of gravity.
part A : calculate the tension T in the rope if the gymnast hangs on the rope
part B: calculate the tension T in the rope if the gymnast climbs the rope at a constant rate
part C : calculate the tension T in the rope if the gymnast climbs up the rope with an upward acceleration of magnitude 1.50m/s/s
part D: calculate the tension T in the rope if the gymnast slides down the rope with a downward acceleration of magnitude 1.50m/s/s
If a ball is thrown upwards at 20 ft/sec, the height h after t seconds is given by h = -16t^2 + 20t. How many seconds does it take for the ball to reach its greatest height, and what is this height.
You and a friend each drive 67 km. You travel at 88.1 km/h, your friend at 952.6 km/h. How long would your friend wait for you at the end of the trip.
