Question

R 4. a) Look at the picture given on the right Drive an expression for the maximum speed of the car (a) in terms of the radius of the curve (R), the gravitational acceleration (g), and the coefficient of friction (): so that the car does not fly off the road.

In question 2,objects which are feather and bowling ball make free fall.

Answer 1

Fc = mv² R ung = mv2 Ffuction = elong Vimana = JURg = Jurg. ma R Vmax more Air resistance causes feather to fall slowly than ball as ball is more dense b) Both would fall with same speed Faur - Fg = ma Faura ta without aur resistance cal Fg CS Scanned with CamScanner
