In a shipping company distribution center, an open cart of mass 51.0kg is rolling to the left at a speed of 5.50m/s (see the figure). You can ignore friction between the cart and the floor. A 10.0kg package slides down a chute that is inclined at 37degrees from the horizontal and leaves the end of the chute with a speed of 2.60m/s . The package lands in the cart and they roll off together.

(a) If the lower end of the chute is a vertical distance of 4.00 above the bottom of the cart, what is the speed of the package just before it lands in the cart?

ans: 9.23m/s

(b) What is the final speed of the cart?

ans: 4.26m/s

The attempt at a solution

I think this is a prefectly inelastic collision when the package falls into the cart.

For first part, is it use v^2 = u^2 + 2as?

where u = 2.6m/s and a = -9.8 and s = -4?

i get the answer 9.23, but i not sure if this is correct cos i din take into acct that the package falls from a slope at an angle. does the angle matter?

For 2nd part, i duno how to do. I tried using conservation of momentum but i cant get the answer.

my eqn is: Mp * Vpi + McVci = (Mp + Mc)Vf

and i get Vf as 5.02m/s

Pls help me.. Thanks!
