A 25,000 kg jet is sitting still on the runway (O m/s). If the jet goes to take off and reaches 80
m/s in 10 seconds, how much force was required
to get it there?

The force required to get it there is 200000 N.

Explanation:

The force can be calculated by the second Newton's law:

Where:

m: is the mass = 25000 kg

a: is the acceleration

The acceleration is given by:

Where:

v: is the velocity = 80 m/s

t: is the time = 10 s

Hence, the force is:

Therefore, the force required to get it there is 200000 N.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
