Answer:

A) True

C)True

D)True

Explanation:

As we know that power is the rate at which work is done.

We know that mechanical work w given as

w = ∫F.ds

F=Force

ds = Elemental displacement

So power P = F.V

V=Velocity

F=Force

The unit of power in SI unit is Watt or joule per second (J/s).But on the other hand the unit of power in English system is horsepower.

The is also can be defined as the rate at which energy is transformed.

Following option are corrects

A) True

C)True

D)True

Someone help please by providing work and answers please :)

First we gotta use an equation of motion:

$d = ut + \frac{1}{2} a {t}^{2}$

Our vertical distance d= 100 m, initial vertical speed u = 0 m/s (because velocity is fully horizontal), and vertical acceleration a = 9.8 m/s2 because of gravity. Let's plug it all in!

$100 = 0 + \frac{1}{2} (9.8) {t}^{2}$

Now we just need to solve for t:

${t}^{2} = \frac{2(100)}{9.8} \\ \\ t = \sqrt{\frac{2(100)}{9.8}}$

Hit the calculators, and you'll get 4.5 seconds!
