Tarzan, who weighs 900N, swings from a cliff at the end of a 40.0 m vine that hangs from a high tree limb and initially makes an angle of 60.0 degrees with the HORIZONTAL. Assume that an x-axis extends horizontally away from the cliff edge and a y-axis extends upward. Immediately after Tarzan steps off the cliff, the magnitude of the total (net) force on the Tarzan is 451N. Assume, the maximum allowed tension on the vine is 770N and Tarzan is intact after he steps off the cliff
a.) What is the magnitude of the tension on the vine.
b.) What is the angle of the net force relative to the positive x-direction?
c.) What is the magnitude of Tarzan's acceleration?
Suppose you have an electric hot water heater for your house which is an aluminum cylinder which has a 0.46 m radius and is 2 m high. How much energy is lost through the walls of the hot water heater
a) Write an expression for the magnitude of the force, F, that propels the dragster forward in terms of the variables provided. b) If the track has length L, select the correct symbolic equation for how fast Vf the dragster is traveling when it fi..
