Default physics question please!?

A crate with a mass of 150 kg is placed on soft ground that sinks under the weight of the box at 0.5 m/s2. How much force is the box exerting on the ground? (g = 10 m/s2).


Really need help with this one as well. Greatly appreciated!

A force of 10 N applied to a block of ice with a mass of 10 kg moves it over a factory floor with a constant speed. What is the coefficient of kinetic friction between the block and the floor? (g = 10 m/s2).
