What is the orientation of the magnetic field in this diagram?

The man fires an 80 g arrow so that it is moving at 80 m/s when it hits and embeds in a 8.0 kg block resting on ice. how far will the block slide on the ice before stopping? a 7.1 n friction force opposes its motion.

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

Modify the equation fδt=δ (mv) to find the force of friction.
