please HELP!!!
What is the magnitude of the momentum of a baseball (m = 1.450 kg) traveling at a speed of 102 mi/h? Express your answer in SI units.
I am unsure where to start

To answer this question, you need to convert the speed of 102 mi/h into the appropriate SI unit (i.e. m/s) and then use the equation for momentum, which is p=m*v, where m is the mass of the baseball (1.450 kg) and v is its speed. So, you would calculate the momentum in kg*m/s as follows: Momentum = 1.450 kg * (102 mi/h * 1.609 km/mi * 1000 m/km)/(3600 s/hour) = 670.57 kg*m/s
