We need to find the speed at the bottom of the slide. Let the speed be v. We can find it using the conservation of energy such that,
Put all the values,
So, her speed at the bottom of the slide is equal to 6.72 m/s.
Answer:
(0.25X+25)N
Explanation:
-let the weight of the box be X.
-Given that the the force needed is equal to one half the weight of the box plus 25N:
Hence, the total force needed is (0.25X+25)N
Answer:
P = E / t definition of power is energy / unit time
1 W = 1 Joule / sec definition of 1 Watt of power
E = 2.6E4 J/s * 30 s = 7.8E5 Joules = 780,000 Joules
