Do an x and y momentum balance and solve for the x and y components of the ball (vx,vy)
Momentum before = momentume after for system of pin and ball:
x (7.5 kg)(6.42 m/s) = (1.6kg)(14.8 m/s)cos(-47) + (7.5kg)vx
y: 0 = (1.6kg)(14.8 m/s)sin(-47) + (7.5kg) vy

I would greatly appreciate it!!

I spent time laying it out for you and I am sure that this is the same as what your teacher does - work on interpreting it. We are not supposed to do assignments. There is nothing but algebra left to do. For the y component, you get - (1.6)(14.8)sin(-47) / 7.5 = -2.31 m/s. Often you solve for the magnitude and angle, but the question asked for the x and y components of v.

Could you provide the answer for both x and y components directly,my teachers formula and explanation is a bit different than yours .If you wouldn’t mind:)!03/10/22
