Question
A 9.7-kg watermelon and a 7.1-kg pumpkin are attached to each other via a cord that wraps over a pulley, as shown. Friction is negligible everywhere in this system.
The angle beneath the pumpkin is 53 degrees and the angle beneath the watermelon is 30 degrees.
(a) Find the accelerations of the pumpkin and the watermelon. Specify magnitude and direction.
magnitude direction
pumpkin: ______ m/s squared direction: up the ramp/down the ramp
watermelon: : ______ m/s squared direction: up the ramp/down the ramp
(b) If the system is released from rest, how far along the incline will the pumpkin travel in 0.30 s?
_____
(c) what is the speed of the watermelon after 0.20 s?
_______
Thank you very much in advance. I think I know how to do part b and c, I just don't know how to find the acceleration. thanks a lot.
