Suppose you set up an experiment using a 2.2 meter long track. The track is inclined at a 10 degree angle. If 1.5 kg cart is initially 25 cm from the upper end, what is its initial GPE? (Show your work please and use units!)
-
the vertical height of the cart is (2.2 - 0.25)*sin10°
GPE = mgh = 1.5 kg*9.81 m/s^2*1.95*sin10 = 4.982 J
GPE = mgh = 1.5 kg*9.81 m/s^2*1.95*sin10 = 4.982 J
