Answer:
Explanation:
which is the final velocity minus the initial velocity in the numerator, and the change in time in the denominator. For us:
so
a = .92 m/s/s (NOT negative because you're speeding up)
The answer would be:
Houlette de berger.
Assuming you are asking about some sort of oscillation, the magnitude of the net force is maximum where the acceleration of the object is the largest. The velocity of an object is maximum where the acceleration is zero.
Answer:
160 watts.
Explanation:
Remark
Power = Work / Time
Work = F * d
Note: Since he is running up stairs he is doing work against gravity.
Givens
- m = 50000 g kg / 1000 grms
- m = 50000 / 1000 = 50 kg
- h = 4 m
- time = 12.5 seconds
- g = 10 m/s^2
Formula
- P = W * d/t
- W = m*g *d / t
Solution
- P = 50kg * 10 m/s^2 * 4 m / 12.5
- <em><u>P = 160 watts. </u></em>
