What is the net force needed to lift a full grocery sack weighing 210N uniformly?
Alex
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.

On a frozen pond, a 10.3 kg sled is given a kick that imparts to it an initial speed of vo = 1.64 m/s. The coefficient of kineti
alukav5142 [94]

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
