D Question 3 10.5 pts A mass of 10 kg lies on a horizontal surface with friction, initially at rest. The coefficient of static friction is 1.47 and the coefficient of kinetic friction is 0.75. One force of 19 Newtons is applied to it upwards (in ty direction). If a force of 13 Newtons is applied in the +x direction, what is the amount of friction acting on the mass in Newtons? Question 4 10.5 pts A mass of 7 kg lies on a horizontal surface with friction, initially at rest. The coefficient of static friction is 1.49 and the coefficient of kinetic friction is 0.77, One force of 19 Newtons is applied to it upwards 0in y directionl. If a force of 218 Newtons is applied in the +x direction, what is the amount of friction acting on the mass in Newtons?Explanation / Answer
3.along y axis,
Fnet = N + 19 - (10 x 9.8) = 0
N = 79 N
maximumf friction force = us N =116.13 N
kinetic friction force = uk N = 59.25 N
along x axis,
Fnet = 13 -f = 0
f = 13 N that is less than maximum friction force.
hence f = 13 N .......Ans
