How long must a force F be applied to a mass M to change the velocity of the mass by 2 m/s if

· F = 1471 N

· M = 153 kg

You know that F=ma.

Therefore, you can easily calculate the acceleration.

Once you know the acceleration, a, you just need to use

\Delta v = a \cdot \Delta t,

where \Delta v is the change in velocity and \Delta t is the amount of time that passes. All you have to do is solve for \Delta t.

Can you do that?
