a 50 kg block is being pulled up a 37 degree incline with a force of 450 N applied parallel to the incline. The block moves at a constant velocity. What is the kinetic friction? power if the velocity is 1.5 m/s? acceleration if the applied force increases to 500N?

Answer 1

IF:-
F=450N, M=50kg, & V=1.5m/s
to find *Friction, *Power, & *Acceleration if the applied force increases to 500N
:-friction=applied force/normal force =f/450, f=mgsin€, =50*10sin€=300
:-friction=450/300=1.5
power=work/time, workdone=mg
:-50*10=500
acceleration if force is 500N
f=ma, a=f/m
:-500/50=10
