1. I am looking to verify my calculation. Question A vehicle of mass 5Tonnes is traveling with a velocity of 80kmh-1 if it needs to stop within a dstnace of 0.5 km using a constant braking force what is the deceleration of the vehicle
2. V^2 = 2xSxA, A=V^2 / 2S
3. A=V^2/2s
80kmn = 22.222ms
A=22.222^2/2x500
A=493.8/1000
A=0.494
Deceleration = - 0.494
2. V^2 = 2xSxA, A=V^2 / 2S
3. A=V^2/2s
80kmn = 22.222ms
A=22.222^2/2x500
A=493.8/1000
A=0.494
Deceleration = - 0.494
