A car of mass 1000 kg travels at 12 m/s on a horizontal and the resistance to motion is 500 N. Find (a) its momentum.
Step 1: Given data
Mass of the car is,
Velocity is,
Resistance (force) is,
Step 2: Calculating momentum
Momentum is given as,
where, is mass and is velocity.
Substituting the known values, we get,
Therefore, momentum is .
