You thought of trying a sled push with 200 kg on a horizontal surface. The co-efficient of static friction between the sled and the gym floor is = 0.8 and the co-efficient of kinetic friction is = 0.6.

i. Draw a Freebody diagram for the sled.

ii. What is the minimum force necessary to make the sled move?

Iii. If you apply a force of 1250 N will the sled move. What is the value of the static friction acting at this point?

iv. If you apply a force of 1800 N find the acceleration of the sled (remember now the sled is moving)
