Answer:
The answer is 53.13
Explanation:
Cuz it is. It's not that hard
Answer:
-3.5 m/s²
Explanation:
- Initial Velocity = 21m /s
- Final velocity = 0m/s
- Distance = 63 m .
- Acclⁿ = ?
<u>We </u><u>know</u><u> </u><u>that</u><u> </u><u>:</u><u>-</u><u> </u>
Stopping distance = u²/2(-a)
63m = (21m/s)² / -2a
a = - 21 * 21 / 63 * 2 m/s²
a = - 3.5 m/s²

Answer:
C. An inital volocity that is faster than the final volocity
Explanation:
.
A baseball traveling at 100 mph has more kinetic energy than a baseball traveling at 50 mph because the kinetic energy = 1/2 x mass x velocity. Since the baseballs should have the same mass, the velocity is what will determine which ball has more kinetic energy. Since the 100 mph baseball has a higher velocity than the 50 mph baseball, it has more kinetic energy.
