I believe that is true. Anaerobic means without (much) Oxygen. This usually builds up lactic acid in muscles.
Answer:
It will take 0.46 seconds to reach home plate by ball.
Explanation:
Answer: 4.77m/s
Explanation:
According to the law of conservation of momentum which states that the sum total of momentum of bodies before collision is equal to the sum of their momentum after collision. Note that the two bodies will move at a common velocity after colliding.
Let m1 and m2 be the mass of the first and second railroad cars
u1 and u2 be the velocities of the railroad cars
v be the common velocity
Using the formula
m1u1 + m2u2 = (m1 +m2)
m1 = 1.20×10⁴kg
m2 = 1.20×10⁴kg (body of same mass)
u1 = 7.70m/s
u2 = 1.84m/s
v = ?
(1.20×10⁴×7.7) + (1.20×10⁴×1.84) = (1.20×10⁴ + 1.20× 10⁴)v
9.24×10⁴ + 2.21×10⁴ = 2.4×10⁴v
11.45×10⁴ = 2.4×10⁴v
v = 11.45×10⁴/2.4×10⁴
v = 4.77m/s
The velocity of the cars after collision will be 4.77m/s
After the ball leaves the bat, the only forces on it are air resistance and gravity.
Answer:
3,00,000
Explanation:
because 1 m =100m so, 3000x100=300000
