Question

Question: A truck driver slams on the brakes and the momentum of the truck changes fromtoindue to a constant force of the road on the wheels of the truck. As a vector, write the net force exerted on the truck by the surroundings.

Short answer

The net force exerted on the truck by the surrounding isN

Step-by-step solution

Definition and the formula of the net force

The rate of change of a particular system’s momentum will be equated to the net force applied to that system.

If the system's momentum changes from initial momentum to final momentum over time , the force acting on the system will be,

${\overrightarrow{F}}_{net}=\frac{{{\displaystyle \overrightarrow{P}}}_2- {{\displaystyle \overrightarrow{P}}}_1}{∆t}$

Finding the net force on the system

Substitute for${\overrightarrow{P}}_1$, for ${\overrightarrow{P}}_2$, and $4.1s$for$∆t$$∆t$

into the formula of the net force acting on the system

Therefore, the net force on the system is
