Best Answer

Acceleration = change in speed/time = (20-5)/3 = 15/3 = 5 units of speed per second. It is not possible to be any more precise because the unit of speed (kilometres per hour, miles per hour, metres per second) is unspecified.

Extremely fast: 1 hour = 3600 seconds speed = distance/time = 1 mi / 45 s = 1/45 mi/s = 1/45 mi/s x 3600 s/hr = 3600/45 mi/hr = 80 mph!

The range is the highest - the lowest. 5:12 - 4 mins 24 secs. This is 48 seconds

It would be 65 MPH.

.66667 miles per hour

Most cars these days have ABS (Antilock Brake System) and they won't leave a skid mark. The speed will be determined by drag from road surface and how efficient the brakes were working. A 100 foot skid on average would be from a speed of 45-50mph on asphalt.

Well speed and acceleration are very different but can be related. Speed is how fast something is going, like 60 miles per hour. Acceleration on the other hand is how fast an object increases, or even decreases speed. Now to apply this practically, if you've ever gotten a ride on a school bus you would notice something different about the way the bus. People often call buses slow but in reality, the bus can reach the same speeds as most normal cars. The difference is that buses take longer to get to that speed. Thus they have a slower acceleration. A normal car can get to 60 miles per hour in about 10 seconds, but a bus may take 15 seconds. So the cars can travel at the same speed, but the car has a faster acceleration.

well we know that we have two speeds and a time. So, initial speed = 80 final speed = 60 change in time = 6 Now acceleration in this case will be measured in kilometers per hour per second (i.e. every x seconds, y kilometers per hour are gained in speed) So we simply apply the formula Acceleration = (final speed - initial speed)/ change in time = (80 - 60)/6 = 20/6 = 3.6666667 km/h/s

The answer will be 5 m/sec/sec 300m/sec - 200m/sec divided by 20 seconds will get you 100m/sec divided by 20 seconds, which then equals 5

Seat belts protect you from the impact of a collision, not from speed or acceleration.

Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2

"Acceleration" means a change of speed or direction. If the direction of your motion changes, then there is acceleration, even if your speed doesn't change.

Using the equation of motion v = u + at. v-the final velocity, u - initial velocity a- acceleration and t-the time.

The car's uniform acceleration is (change in speed) divided by (change in time) = (24 m/s) / (2.95 s) = 8.1356 meters/sec2. Call this number ' A ' for acceleration. Change in speed = ( A ) times (time) Time = (change in speed) / A = (20 - 10) / A = 10/A = 0.81356 seconds (rounded)
