Suppose 500 joules of work is done to push an object in 15 seconds. Find the power for this situation

ohaa [14]

Answer:

You have to calculate

Explanation:

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.

Steelhead trout migrate up stream to spawn.Occasionally they need to leap up small waterfalls to continue their journey. Fortuna

Ainat [17]

Part a)

since steelhead jump under the influence of gravity

So we will use kinematic equations

$v_f^2 - v_i^2 = 2ad$

here at the maximum position we know that final speed will be zero

$v_f = 0$

$a = -9.8 m/s^2$

$v_i = 8m/s$

now we will have

$0 - 8^2 = 2(-9.8)d$

$d = 3.26 m$

so the maximum height that it can reach will be 3.26 m

Part B)

now if it reaches to height 1.8 m with initial speed 8 m/s

so here we will have

$y = v_i t + \frac{1}{2}at^2$

$1.8 = 8 t - \frac{1}{2}(9.8)t^2$

$4.9 t^2 - 8t + 1.8 = 0$

$t = 0.27 s$
