A bullet of mass 20 g is found to pass two points 30 m apart in a time interval of 4 second. Calculate the kinetic energy of the bullet if it moves with constant speed.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
( 
= 0.5625 J)
Sol. v = 
= 
= 
m/s
K.E. = 
mv 2 = 
× 20 × 10 –3 × 
= 
J.
