Answer: 7 kg bowling ball must move with a speed of 2.8 m/s so that it has the same kinetic energy.
Step-by-step explanation:
Kinetic energy is the energy possessed by a body by virtue of its motion.
m = mass of object
v= velocity of the object
b) for a 7 kg bowl to have kinetic energy of 27 Joules:
Thus 7 kg bowling ball must move with a speed of 2.8 m/s so that it has the same kinetic energy
