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
hope it helps :)
