a)calc the forward driving force acting on the car while it is accelerating.

b)At high speeds the resistive frictional force F produced by the air on a body moving with velocity V is given by the equation F=bv^2 where b is a constant.

i)Derive the base units of force in the SI system.

ii)Determine the base units of b in the SI system.

iii)The car continues with the same forward driving force and accelerates until it reaches a top speed of 50ms.At the speed the resistive force is given by the equation F=bv^2.Determine the value of b for the car.

**Marshall**, Thursday, March 15, 2012 at 6:06pma) First calculate the acceleration a=(8-0)/2,0=4ms^-2

therefore force (F)=m*a=1200*4

=4800newtons
