How much force is needed to bring a car to a halt over 5 seconds - the car is moving with velocity km/hr and with a mass of 1000kg.

Explain the concept of momentum mathematically, then draw on physical intuition to reaffirm/deepen their understandingDiscuss how there exists a relationship between the rate of change of momentum and forceUse this to produce an equation for the forceCalculate the force - but first units need to be converted to standard unitsAsk them a similar question and ask if they'd like to go through it themselves
