a = (vf - v0)/Δt
10 mph/s = (45 mph - 20 mph)/Δt
Δt = 2.5 s
As long as the 30 minute are spent driving in a straight line, the acceleration is zero.
It all depends upon the acceleration. A fast car can probably do it in under 10 seconds. Driving economically would take much longer. A jet plane can do it quicker.

It could be anything you want as long as you and the audience understands it. Convention, however, usually shorthands force as 'F'. Newton's 2nd law: F=ma Force is the acceleration of a mass.
It would be 3/8 of an inch long or wide.

About .0011111 hours, or about 4 seconds.This is assuming the units are miles/(hour*sec), which converts to 36000 miles/(hour^2) as the acceleration.
Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds
There is no such thing as 20 mph acceleration. 20 mph is a velocity. Acceleration is expressed as velocity per unit time e.g. mph per second or mph per minute etc.
depends on how long it takes to accelerate from these speeds (45m/s-25m/s)/time(s)
The formula for finding time based on acceleration and speed is: (Delta)t = (Delta)v/a Change in time = change in speed / acceleration t = 75-15 / 20 t = 60 / 20 t = 3 seconds
Depends on the rate of acceleration (km / h) / second
If an object moved with constant acceleration it's velocity must ?
It would depend on the vehicle.
A bullet does not accelerate after it leaves the barrel of a gun. It will decelerate. You could say it accelerates, but the acceleration would be negative. The bullet is accelerated by expanding gas as it moves down the barrel, and after it leaves the muzzle, there is no more acceleration imparted from expanding gas. We also find that air friction (drag) is acting to slow it down. Think this one through and it becomes obvious.
The exchange zone on a 400 meter track is 20 meters long. For races involving 200 meter legs or less, a 10 meter acceleration zone may be marked on the track and used by the runner receiving the baton to accelerate to match speed with the incoming runner. With or without an acceleration zone, the baton must still be exchanged within the official 20 meter zone.
no, the shifting in the automatic works off of RPM's, it will accelerate as long as you have your foot on the pedal. the harder you push, it will down shift and go faster
