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.)

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
