ok I have another problem here. Please help me. Thank you in advance.
A 1.50 kg sled scrapes down a grassy incline where the coefficient of friction is 0.678. The sled moves at a constant speed f 4.50 m/s and it takes 12.5 seconds to travel the entire length of the hill to the bottom.
After the sled passes, a 5.00kg rolling cart (with an effective coefficient of friction of .456) goes down the same hill. At the bottom. the cart crashes into a very massive bale of hay (which does not move so this is not a collision problem). The ha bale exerts an average force of 98.0N on the cart. Calculate how far into the hay bale the cart goes before stopping.
[Hints: find angle of incline; length of incline; acceleration of cart; speed at bottom of incline]
I received for the angle: 34 degrees
the length of the incline: 2.78m
acceleration of cart: 1.78m/s squared
speed at bottom: 3.15 m/s
Please inform me if I am wrong on any of those, and please help me to calculate the distance the cart travels in the hay before it stops.
