What angle does the rain make with the vertical as the driver looks out the window horizontally and perpendicularly from the path of the car. 6.

Explanation / Answer

let the initial velocity of the body is Vo

and after travelling a distance x,the body has final velocity V,with the accelaration a in time t seconds

then

average velocity = distance travelled / time taken

(V+Vo)/2 = x/t

but accelaration is a = rate of change of velocity = (V-Vo)/t

then t = (V-Vo)/a

(V+Vo)/2 = x*a /(V-Vo)

doing cross multimplication we get

(V+Vo)*(V-Vo) = 2*a*x

V^2- Vo^2 = 2*a*x

V^2 = Vo^2 + (2*a*x)
