Answer: 7 kg bowling ball must move with a speed of 2.8 m/s so that it has the same kinetic energy.
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
For this problem, you would use the equation v=u+at. In this case, u=1 v=0 (when the object is at rest) a=-1
v=u+at
0=1+(-1)t
t=1 second
Answer:
If there is no horizontal component to the force then it is just 0N
