Margaret walks to the store using the following path: 0.740 miles west, 0.300 miles north, 0.240 miles east. Assume north to be along the +y-axis and west to be along the -x-axis

whats the direction of displacement vector

A block with mass m is dragged across a horizontal surface at constant speed v by a force of magnitude Fapp, which acts at an angle of θ above the horizontal surface. The coefficient of kinetic friction between the block and the surface is coefficient of kinetic friction µ_k. The normal force exerted on the block by the horizontal surface is:

A tiger leaps horizontally from a 7.5 m high rock with a speed of 4.5 m/s. how far from the base of the rock will the tiger land?

1. Differentiate between distance and displacement.
2. Differentiate between instantaneous speed and average speed.
3. Differentiate between speed and velocity. 
4. Differentiate between momentum and inertia.
