A speedboat with a mass of 505 kg (including the driver) is tethered to a fixed buoy by a strong 29.7 m cable. The boat's owner loves high speed, but does not really want to go anywhere. So the owner revs up the boat's engine, makes a lot of noise, and runs the boat in circles around the buoy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 12300 N, with what force is the boat's engine pushing the boat? Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m) x v, where v denotes the boat's speed. Ignore any drag force on the cable. force: N I TOOLS x10

Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m) × v², where v denotes the boat's speed. Ignore any drag force on the cable.

[There is an input box for force with units in Newtons, and a tool button labeled "×10^."]

A teacher pulls a crate of mass M up the inclined surface the distance d. The surface rises 0 degrees above the horizontal, as shown in the figure. How much does the gravity do on the crate? M=11.9 kg, 0=26.9 degreees, d=5.88 m, g=9.80 m/s^2
A 61.9-kg circus performer is fired from a cannon that is elevated at an angle of 57.3 ° above the horizontal. The cannon uses strong elastic bands to propel the performer, much in the same way that a slingshot fires a stone. Setting up for this stunt involves stretching the bands by 2.35 m from their unstrained length. At the point where the performer flies free of the bands, his height above the floor is the same as that of the net into which he is shot. He takes 3.02 s to travel the horizontal distance of 28.7 m between this point and the net. Ignore friction and air resistance and determine the effective spring constant of the firing mechanism.
