Force required to stop the Car (using MathCAD)
A car mass 1500kg is moving with a velocity of 50 km/h. What is force required to stop the car at a distance of 100 m?
The velecity of 50 km/h is equal to 13.89 m/s, using Mathcad type v:50km/hr=
The kinetic energy T is
first define the variabel m, type m.car:1500kg
type T.car:1/2 space *m.car*v^2=
The force F required to stop the car can be obtained by equating Fx (where x is the distance) and T.
type F*x ctrl = T.car
to solve the F, after type type F*x ctrl = T click solve from this toolbar
you will get this
type F and click Enter on your keyboard, mathcad will show the value of F
create variabel x to solve F above the equation by typing x:100m enter and you should get like this
Now, copy the result and click enter to find final answer
and this is Mathcad project that have been created
