Question

(a) A boat with a horizontal tow rope pulls a water skier. She skis off to the side, so the rope makes an angle of 19.0 degree with the forward direction of motion. If the tension in the rope is 164 N how much work does the rope do on the skier during a forward displacement of 300.0 m? (b) A bullet is fired into a large stationary absorb rand comes to rest. Temperature measurements of the absorber show that the bullet lost 1960 J of kinetic energy, and high speed photos of the bullet show that it was moving 995 m/s at just as it struck the absorber. What is the mass (in grams) of the bullet? Equation(s) Solution/Work:

Explanation / Answer

According to the chegg guidelines I am allowed to answer only 1 question at a time.

1) Provided values theta = 19 deg T = 164 Newton d =300 m

Work done = fd cos (theta ) =164 * 300 * cos ( 19 deg ) = 46519.51392 Joule ==============ANSWER)
