Hi. I am currently doing a homework assignment that has me completely stumpe

It involves being presented with a limited set of specs and data for an electric motorcycle that needs a battery pack. I did fine with the battery calculations but am really struggling with the rest. The calculations i need to figure out how to do are.

- Acceleration

- Range of vehicle

Data given is

Mass = 163kg

Wheel radius = 0.305kg

Max speed = 90kph

(v)Average speed = 30kph

Average power required to maintain speed = (Mass*v^2*(f)) in Watts

(f) Energy usage fraction = 12%/s

Expected usage and recharges = 5 recharges a week for 50 weeks a year

Motor input power rating = 17.5kW

Nominal Voltage= 48V

Nominal Torque = 68.4Nm

Motor Efficiency = 90%

Any help or pointers as to how i would solve this to get the acceleration and range would be great!!!! Thanks in advance
