Calculating Time to reach 60 mph

[sadhik]

In the given table how to calculate the time 0-60 mph(seconds)

 

[redargon]

ummm, there is certainly not enough information there to calculate a 0-60 time.

unless you're assuming that all power is used 100% efficiently for forward motion and neglect things like friction, gearing, aerodynamics etc etc etc

 

[redargon]

you could probably roughly use P=E/t and E=1/2*mv², but you're going to have to get some common units.

60 miles = 316800 ft
So initial velocity(u) = 88 ft/sec

Weight = 3320 lb
?Mass(m) = 3320/32 =103.75 lb

?Any chance to get Acceleration(a) from Power:Weight = 0.13554217 hp/lb

?Velocity(v)

 

[redargon]

well, actually your initial velocity (u) is zero and your final velocity is 60mph

I think they actually mean mass when they say weight in lbs, especially if they're talking about a car, 3320lb mass seems reasonable.

I'm not sure how the US units work so well, so here are the metric standards:
Power - Watts (W)
Energy - Joules (J)
Velocity - metres per second (m/s)
Mass - kilograms (kg)
Force - Newtons (N)
time - seconds (s)
Acceleration - metres per second squared (m/s²)

Try find the equivalent standard units for your unit system or convert everything to metric and try it like I wrote previously.

?Final Velocity(v)=60 mph=3801600 inches/h=96560.8331 m/h=26.8224537 m/s

?Mass(m)=3320 lb=1505.92656 Kg

?Energy=1/2 mv^2=541714.97 Joules

?Power=450 HP=335700 Watts=541714.97 Joules / t
