A go-cart of mass 250 kg has a maximum acceleration of 4 m s2. (a) Show that the maximum force the engine can achieve is 1 kN. (b) The drag Don the go-cart is given by the equation where A is a drag coefficient of 0.918 kg m1. Calculate the maximum speed of the go cart on level ground if-ground friction can be taken as negligible.12 marlkc) Use the information in parts (a) and (b) to determine the maximum acceleration of the cart when it is travelling at 10 m s.
