A car with a total mass of 1400kg (including occupants), traveling at 60kmh^-1 hits a large tree and stops in 0.08seconds. What is the magnitude of the deceleration of the 70kg driver of the car if he is wearing a properly fitted seat belt?

Explanation:
Using the kinematic equation
#v=u+at#
where symbols have their respective meanings. Inserting given values in SI units, and assuming that deceleration is constant, we have
This is deceleration of car, its occupants including driver.
