Therefore, the acceleration of the car is
0.07 m/s 2
.
What is the acceleration of a car if the speed of the car has increased from 25 km per hour to 50 km per hour in one minute?
Answer: accleratiin equals to change in speed by time. A=40-25/60 . 15/60=1/4=
0.25m/sec^2
.
What is the acceleration of a car if the speed of the car has increased from 25km per hour to 40km per hour in one minute?
A=40-25/60 . 15/60=1/4=

What is the acceleration of a car that maintains a constant velocity of 55 m/s for 10 seconds?
20. What is the acceleration of a car that maintains a constant velocity of 55 mi/hr for 10.0 seconds? If the velocity is constant, then there is no acceleration. That is, the value of the acceleration is
0
.
How Can acceleration be calculated?
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation
a = Δv/Δt
. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
What is the formula of retardation?
a = Change in velocity/Time taken
So, you can get a negative acceleration value in the case of v<u, that is is known as retardation.
How do you find acceleration with speed and distance?
Answers and Replies
You could use the formula (distance)=(initial velocity)*t + (
1/2
)*(acceleration)*t^2 to find the time, using initial velocity = 0, acceleration = -9.8 and distance = 4.7. Then you could use the formula (final velocity)-(initial velocity) = (acceleration)*t, using the same acceleration and time.
What constant acceleration is required to increase the speed?
An acceleration of
8.8 ft/s^2
is required to increase the speed from 26 mi/hr to 56 mi/hr in 5 s.
What is the maximum acceleration of a car?
A: You’re right that the maximum acceleration for some cars can be in the neighborhood of g,
9.8 m/s
2
. That means that the coefficient of friction, μ, has to be around 1 or so.
Which car accelerates fastest?
Its terminal speed as it crossed the quarter-mile marker was 167.51 mph. This allowed the 1,914 hp Rimac to officially claim the title of being the world’s fastest accelerating production car.
What three things happen during acceleration?
There are three ways an object can accelerate:
a change in velocity, a change in direction, or a change in both velocity and direction
.
What is the average acceleration formula?
Average acceleration is the rate at which velocity changes: –
a=ΔvΔt=vf−v0tf−t0
, where −a is average acceleration, v is velocity, and t is time. (The bar over the a means average acceleration.)
What is constant speed?
Definition:
When the speed of an object remains the same
– it does not increase or decrease – we say it is moving at a constant speed.
What is the acceleration of a car that can go from rest to 100 km/h in 10s?
Since (average) acceleration = (change in velocity)/(time it takes), the car’s acceleration = (100 km/h)/(10 s) =
10 km/h/s
.
