Answer:
750 J
Explanation:
lets convert mass into kg first , 150 /1000 = 0.15 kg
kinetic energy =
= ![\frac{0.15*100^{2} }{2} = 750 J](https://tex.z-dn.net/?f=%5Cfrac%7B0.15%2A100%5E%7B2%7D%20%7D%7B2%7D%20%20%3D%20750%20J)
Answer:
3000 hurs
Explanation: just divide 150000 by 50 and get 3000
The magnitude of the average impulsive force imparted to the ball if it is in contact with the bat is 6000 N
The mass of the baseball, m = 0.15 kg
The speed at which it moves, v = 30 m/s
Time at which the baseball was in contact with the bat, t = 0.75 ms
t = 0.75/1000 s
t = 0.00075 s
The impulsive force is given by the formula:
![F=\frac{mv}{t}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7Bmv%7D%7Bt%7D)
Substitute m = 0.15 kg, v = 30, and t = 0.00075s into the formula above:
![F=\frac{0.15 \times 30}{0.00075} \\\\F=6000N](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B0.15%20%5Ctimes%2030%7D%7B0.00075%7D%20%5C%5C%5C%5CF%3D6000N)
The magnitude of the average impulsive force imparted to the ball if it is in contact with the bat is 6000 N

Answer:
Potential gravitational energy is the energy that the body has due to the Earth's gravitational attraction. In this way, the potential gravitational energy depends on the position of the body in relation to a reference level.
