How to calculate impulse

  1. Aug 17, 2005 #1
    If you know the mass of an object and the speed of its motion, how do you calculate how large the impulse is when it is caught or stopped?

    The impulse is simply the change in momentum.

    Do you know how to calculate momentum?

    yes, momemtum is p=mv, which would give me the "t" for impulse = Ft which would give me the impulse?

    As brewnog stated, the impulse equals the change in momentum. What's the change in momentum when the object is brought to rest. (No need to use F or t, luckily, since these are not given.)
