I believe the acceleration would be 5m/s
All you would need to do is divide the final speed by the time it took to get there. I am only about 80 sure this answer is correct, so take my advise only if you feel comfortable.
Answer: 87500J
Explanation:
Given that,
Power exerted by crane = 3,500 W
Time taken = 25 seconds
work done by crane = ?
Since power is the rate of work done per unit time, then power is workdone by the crane divided by the time taken.
i.e power = work / time
3,500 W = work / 25 seconds
Work = 3500W x 25 seconds
Work = 87500J
Thus, 87500 joules of work was done by the crane.
Separation of light into different color is called "dispersion". Rainbow, comes from refraction and reflection of sunlight, in the falling raindrops, which means that that the refractive index of water depends on the wavelength of light.
Answer:
Distance travel s = 296.8 m
Explanation:
Given:
Initial velocity u = 6.5 m/s
Constant acceleration a = 2.1 m/s²
Time T = 14 s
Find:
Distance travel s
Computation:
s = ut + (1/2)at²
s = (6.5)(14) + (1/2)(2.1)(14)²
s = 91 + 205.8
Distance travel s = 296.8 m
