How long would it take a car to accelerate from 10 mph to 45 mph if it's acceleration is 20 mph?
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.
How long would it take a car to accelerate from 15 MPH to 75 MPH if its acceleration is 20 MPH?
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
How long does it take to drive 1km?
It depends on the speed/acceleration.
How can you find velocity from only force and mass?
You would need to use the equation f=ma In this equation, f means force, m means mass, and a means acceleration. So dividing the force by the mass will give you a figure for acceleration. If you know how long the object has been accelerating for, or how far, and what the initial velocity was (or whether it started off still) then you can work out the velocity from this acceleration.
What is the maximum acceleration of a train with a maximum speed of 90 miles per hour?
You have to know how long it takes to get to 90 mph to solve this. Speed = acceleration x time
How long would it take a car to accelerate from 20 mph to 60 mph if its acceleration is 10 mphsec?
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.
How long would it take a car to accelerate from 20 mph to 45 mph if its acceleration is 10 mphsec?
a = (vf - v0)/Δt 10 mph/s = (45 mph - 20 mph)/Δt Δt = 2.5 s
How long would it take a car to accelerate from 10 MPH to 75 MPH if its acceleration is 20 MPHs?
Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds

How long does it take to accelerate from 90 kilometers per hour to 120 kilometers per hour?
Depends on the rate of acceleration (km / h) / second
What happens with forces are unbalanced?
When forces are unbalanced, there is a net force causing an object to accelerate in the direction of the greater force. This acceleration can result in a change in the object's speed, direction, or both. The object will continue to accelerate as long as the forces remain unbalanced.
If an object starts to accelerate?
If an object moved with constant acceleration it's velocity must ?
What happens when unbalenced force acts on an object?
When an unbalanced force acts on an object, it causes the object to accelerate in the direction of the force. This acceleration could result in the object moving faster, slowing down, or changing direction. The object will continue to accelerate as long as the unbalanced force is applied.
How long does it take to accelerate from 0 mph to 40 mph?
It would depend on the vehicle.
When a constant force acts on a mass starts moving from rest then the?
acceleration of the mass will be constant until another force acts on it, causing a change in acceleration. The mass will continue to move in the direction of the force until an opposite force is applied.
What is acceleration zone in track and field?
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.
