Problem 7P

Estimate the pressure exerted on a floor by (a) one pointed chair leg (60 kg on all four legs) of area = 0.020 cm2, and (b) a 1500-kg elephant standing on one foot (area = 800 cm2).

Step-by-Step Solution:
Step 1 of 3

ANSWER: To answer which one has more kinetic energy, first we need to calculate the kinetic energy for each. So, let’s do it. STEP 1:- The kinetic energy of the bullet of 10 g fired at a speed of 500 m/s is, 3 2 Here the mass = 10 g= 10×10 kg = 10 kg. The velocity is, V = 500 m/s. 2 2 So, K.E = 1/2×10 ×500 = 1250 jules. STEP 2:- The kinetic...
