MCAT Question of the Day
    •

    Q:

    		 A cart is moving toward a hill that is 50 m tall. The cart coasts up the hill but does not reach the top, missing the peak by only a few meters. After rolling back down, the driver doubles the weight of the cart in an attempt to double the momentum and make it over the hill. Which of the following is the most likely result of this strategy, assuming the same velocity is used as in the first attempt? Note: neglect friction and air resistance.
    		 

    A

    		 The cart will reach the top but not make it over the hill

    B

    		 The cart will reach the top and make it over the hill

    C

    		 The cart will reach the same spot it reached before

    D

    		 The cart will not reach as far as it reached before
