      Math Project Automotive Engineering    Home What an Engineer Does Civil Engineering Automotive Engineering Electrical Engineers Conclusion       Automotive Engineers must apply physics to prototype trucks in order to find out if they have enough power to sustain a useable towing capacity.

The equation W=Fd must be applied to this equation. However since we are not given enough information another equation must be substituted in in order to find the equation. Where F=ma is substituted for  F. Than A=V2-V1/T

Work=Force multiplied by distance
Force=Mass multiplied by acceleration
Acceleration=Velocity final minus Velocity initial divided by time.

W=Fd
W=(ma)d
W=(m(V2-V1/t))d

Now that we haveo ur equation we must assume the following since this is only a scenerio:
Mass of the truck will be 3500kg.
Distance will be 100meters
V1=0M/s
V2=5m/s
t=15 seconds

W=(m(V2-V1/t))d
W=(3500)((5-0/15))100
W=(3500)(1/3)100
W=(1166.6)(100)
W=11666joules of energy

This means that the truck must produce 11666 joules of energy to accelerate

at .333 m/s in 15 seconds.

Now that we have found our work we may find out how much power is needed to accomplish this task.

P=W/t
P=11666/15
P=777.73watts of power is used.   Math Assignment 2005 Due March 18th
