The pushing force on the motor bike is 3000 Newtons.
Given the data in the question;
- Power of the engine; [tex]P = 90000W[/tex]
- Velocity; [tex]V = 30m/s[/tex]
Pushing Force; [tex]F = \ ?[/tex]
Power is simply the amount of energy transferred per unit time.
It can be expressed as:
[tex]P = F * V[/tex]
Where F is force applied and V is velocity
We substitute our given values into the equation
[tex]90000W = F\ *\ 30m/s\\\\90000 kg.m^2/s^3 = F\ *\ 30m/s\\\\F = \frac{90000 kg.m^2/s^3}{30m/s} \\\\F = 3000 kg.m/s^2\\\\F = 3000N[/tex]
Therefore, the pushing force on the motor bike is 3000 Newtons.
