Question

An ox can apply a maximum force of 1000 N , It is taking part in a cart race and is able to pull the cart at a constant speed of 30ms^-1 while making its best effort. Calculate the power developed by the ox.

Answer 1

$<marquee behavior=move bgcolor= Pink > <h1> ☺️☺️Holla ✌️✌️ </h1></marquee>$

Here, F = 1000N ,

v = 30 ms^-1

we know , that power developed ,

P = F × v,

1000 × 30 watt,

= (1000×30)/ 1000

= 30 KW


Thanks!

Answer 2

Given,

Force = 1000 N

Velocity = 30 m/s

As we know that,

=> Power = Force x Velocity

=> P = (1000 x 30) Nm/s

=> P = 30000 Watt

=> P = 30000/1000 KW

=> P = 30 KW
