An athlete in the Olympic games covers a distance of 100 m in 10 s. His kinetic energy can be estimated to be in the range (Assuming mass of athlete is between 40 kg to 100 kg)
Text Solution
Verified by ExpertsThe correct answer is:
C
Assuming mass of athlete is between 40 kg to 100 kg
here we will consider mass of athlete m = 50 kg
m = 50 kg
V = S/t = 
= 10 m/sec
So, K = 1/2 mv 2 1/2 × (50 ×10 2 ) = 2500 J
