Acceleration
Q: Between Hennessey Venom GT and Koenigsegg Agera R, which car has a better acceleration in 5 seconds? A The hennessey Venom Gt would have better acceleration in 5 seconds because it has the higher average acceleration
1. Acceleration is a vector quantity that is defined as a rate of change of velocity within a time using units: m/s/s, mi/h/s, km/hr/s, m/s2 (squared)
A=Δv/Δt
Vf= Vi + gt Vf=Vi+(a)(t)d= 0.5(vi+vf)t d=vi(t)+0.5(a)t²d=vi(t)+0.5(g)(t)² vf²=vi²+2(a)(d)
1st cars acceleration:a=vf-vi = 26.67 - 0 =11.11m/s² T 2.4
2nd cars acceleration:a=vf-vi = 26.67 - 0 =8.89m/s² T 3.0
2. a) aerodynamics (shape of the car and weight): Aerodynamics design of a car body ensures the vehicle to be stable, more safe, less chance of the car to flip
2. b) Carbon Fibre: Carbon fibre is a lighter material and helps lessens the weight of the car. it’s a economic consideration and less fuel consumption
2. c) Spoilers: Spoilers help increase the grip on the road, less drag (somewhat same reason as A)
2. d) Tires: Tire design reduces friction between the tires and the road. The less weight of the tire the better the performance ( safety and economic decision)
2. e) Engine: Engine is part of the factory works design, the engine mostly depends on the performance of the car
Hennessey Venom GT:0 - 96 km/h in 2.4 secTop speed of 437 km/hLength:15.27 ft.Width: 6.43 ftTorque: 1155 lbs/ft
