If the sack weighs 210 newtons, then an upward force of 210 newtons
exactly cancels the downward force of gravity, and makes the net vertical
force on the bag zero.
ANY upward force that's greater than 210 newtons makes the net force
act upward on the bag, and causes it to accelerate upward.

The five-step process for treating a muscle or joint injury such as an ankle sprain is called "P.R.I.C.E." which is short for Protection, Rest, Ice, Compression, and Elevation).

Answer:
d=1.07m
Explanation:
Calculate Initial Kinetic Energy:
KE = 1/2*m*v^2
KE= 0.5*(10.3kg)*(1.64m/s)^2 = 13.85J
Calculate work overcoming friction:
W = F*d = mu*m*g*d
W = (0.128)*(10.3kg)*9.80m/s^2)*d
W = 12.92*d
Equate the two since all of the kinetic energy is used up in working against friction:
W = KE
12.92d = 13.851J
Solve for d:
d= (13.851J)/(12.92) = 1.07 m
