Answer:
A. The tennis ball has more kinetic energy.
Explanation:
kinetic energy is defined as
now we know for baseball we have
m = 0.14 kg
v = 41 m/s
Similarly for tennis ball we have
m = 0.058 kg
v = 67 m/s
So tennis ball will have more kinetic energy then baseball
Answer:
44.8 m/s
Explanation:
Use the Initial Speed Formula:
InS = 2(d/t) - Final Speed
InS = 2(55/1,25) - 43.2
InS = 2.44 - 43,2
InS = 88 - 43,2
InS = 44.8 m/s
Answer:
Explanation:
A lot. That's why he was one of Boston's star hitters.
m = 0.15 kg
a = 3.0 * 10^4
F = ?
F = 0.15 * 3*10^4
F = 0.45 * 10^4
F = 4.5 * 10^3 Newtons
You should always express scientific notation as a number between 1 and 10 or 1 < x < 10. The power will determine the exact value of the number expressed as a scientific notation.
1. Naturally occurring
2. Inorganic
3. Crystalline structure
4. DEFinite chemical composion
5. Solid
