expect to observe in a similar real life scenario and why? Make specific references to ENERGY. b. Imagine in real life there was a coefficient of kinetic friction of 0.4 between the plastic wheels of the cart and the wooden ramp. If there is only friction on the flat part of the track how far would the cart go before it stopped if it started from a height of 4m? Show your calculations c. The cart is set up with a frictionless apparatus as shown in the figure below. If the cart launched from the spring has an initial velocity of 12.3m/s how high up the ramp would it go? Show your work. 5kg Draw a free body diagram of the cart on a frictionless track when: a. The cart is at the top of the ramp before it begins moving b. The cart halfway down the ramp c. The cart on the flat part of the track
