Scientific Theory vs. Law

MATH

1.) A giraffe with uniform acceleration a, starting from rest, will reach a speed of v in time t according to the formula a=(vfinal-vinitial)/time. What is the acceleration of a giraffe who accelerates from rest to 7.00 m/s in 4.00 s?

2.) Pressure equals force divided by area (P=F/A) and force equals mass times acceleration (F=ma). A 53 kg monkey has gravity pulling down on him at 9.8 m/s2. If the pressure exerted on the floor is 32,500 N/m2. What is the area of the soles on his shoes?
