An object of mass 1500g is dropped from a 60m tower on a planet other than Earth. The gravitational force on the object is 4.5N. The gravitational acceleration on this planet ism/s2.

When the object is dropped it has a velocity of 10m/s after 4 seconds. The air resistance must be ___

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
