Engine 1 produces twice the power of engine 2. If it takes engine 1 the time T to do the work W, how long does it take engine 2 to do the same work?
Express your answer in terms of some of all of the variables T and W.
T2=

Explanation:

Given that engine 1 produces twice the power of engine 2.

Let and be the power of engine 1 and engine2.

So, the power of the engine 2,

As, Work = Power x time,

So, the work, W, done by an engine 1:

The work, W, done by an engine 2:

If the work done by both the engines are the same, then

[from (ii) nd (iii)]

[by using (i)]

Hence,

prolly a beacuse the momentuem the car has increases while going down hill

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
