OK I'm stuk on a physics question involving Newton's Laws of motion.
Question:
Boy gives his sister ride on sled by exerting force of 300 N[E].
Frictional resistance amounts to 200 N. If sister and sled have combined mass of 50 kg, and if boy starts from rest and pushes for 5 sec., find:
a) the sled's acceleration
b) velocity attained by sled in 5 sec.
c) distance traveled by sled in 5 sec.
PLZ try to help and show step by step solutions
Reply ASAP thanx
