Question

If it takes 726 watts of power to move an object 36 m in 14 s, what is the mass of the object?

Answer 1

Answer:

Explanation:

Given

Power (p)= 726 watt

Time (t) = 14 sec

distance travelled (d; h) = 36 m

mass (m) = ?

we know

Power (p) = W/t  ( w = work done )

p = m * g * h / t  ( w = m * g* h)

726 = m * 10 * 36 / 14 ( g = 10 m/s^2)

m = 28. 23 kg

or if we use the value of g as 9.8 m/s^2

the mass will be

= 28.8 kg
