The mass of a sports car is 1000 kg. the shape of the car is such that the aerodynamic drag coefficient is 0.260 and the frontal area is 2.10 m2. neglecting all other sources of friction, calculate the initial acceleration of the car, if it has been traveling at 90 km/h and is now shifted into neutral and is allowed to coast. (take the density of air to be 1.295 kg/m3.)

Explanation:

We are given that

Mass of car=m=1000 kg

Drag coefficient,

Frontal area,A=

Speed, v=90 km/h=

Density of air,

We know that

Drag force,

Using the formula

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
