[SOLVED] Concept Question
Q2: Suppose rain falls vertically into an open cart which is rolling along a straight track with negligible friction. The speed of the cart
a. increases
b. decreases
c. doesn't change
Q2: Now that the cart is full of water, you poke a hole in the bottom and the water drains out. What happens?
change in momentum=mv(final)-mv(initial)
For the first question I was able to reason out the the speed of the cart decreases.
For the second question I've hypothesized that the speed increases as the weight decreases.
Could someone please verify if I'm correct or not, and attempt to direct me in the correct direction?
thanks
