3. the mass of aimi is 47kg. she wears a pair of high-heeled shoes, each with a surface area of contact of 1.5cm with the floor. what is the pressure exerted by aimi on the floor? 4. the mass of a car is 1000kg. if the area of contact between the tyres and the road surface is 25cm^2,calculate the pressure exerted by each tyre on the surface of the road.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
