Scooter acquires a velocity of 36 kilometre per hour in 10 seconds after the start it takes 20 seconds to stop calculate the acceleration?

Convert the speeds to meters per second (to convert from kilometers per hour to meters per second, you have to divide by 3.6). You have two accelerations here: for speeding up, and for slowing down. In each case, calculate the change in velocity, and divide that by the amount of time it takes. That's your acceleration, in meters per second squared.

To find the acceleration, we need to first convert the velocity from kilometers per hour to meters per second. 36 kilometers per hour is equivalent to 10 meters per second.
Next, we can use the formula for acceleration: acceleration (a) = change in velocity (Δv) / time taken (Δt).
For the acceleration during the start, the change in velocity is 10 m/s (initial velocity was 0) and the time taken is 10 seconds. Thus, the acceleration is 1 m/s^2.
For the deceleration (when stopping), the change in velocity is -10 m/s (final velocity was 0) and the time taken is 20 seconds. Thus, the acceleration is -0.5 m/s^2. Negative sign indicates deceleration.

Why do you had to calculate acceleration with velocity?
Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.
What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time
How do you calculate acceleration from velocity?
There are 3 formula 1. Final velocity = starting velocity + (acceleration)(time) 2. Final velocity^2 = starting velocity^2 + 2(acceleration)(distance) 3. Distance = (starting velocity)(time) + 1/2(acceleration)(time^2) Use whichever you can use.
How do you calculate acceleration when given velocity and distance?
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
How do you calculate power when given speed acceleration weight and distance?
Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.
Why do you had to calculate acceleration with velocity?
Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.
Is it true that to calculate acceleraltion you need to know both the final and the initial velocity of an object?
No. That's only one of several possibilities. -- with initial velocity, distance, and time, you can calculate acceleration -- with final velocity, distance, and time, you can calculate acceleration -- with force and mass, you can calculate acceleration -- with initial and final momentum, you can calculate acceleration -- with initial and final kinetic energy, you can calculate acceleration -- with mass, velocity at either end, and kinetic energy at the other end, you can calculate acceleration And I'm sure there are several more that I've missed.
''How do calculate velocity?
To calculate velocity using acceleration, start by multiplying the acceleration by the change in time. For example, if the acceleration is 10 m/s2 and the change in time is 5 seconds, then there is a 50 m/s increase in velocity. Then, add the initial velocity to the increase in velocity.
How do you calculate acceleration from distance and time?
Acceleration= Distance/time (distance divided by time) That's the dumbest answer I've ever heard.. Acceleration = Final Velocity - Initial Velocity/Time Velocity = Displacement/Time So you can't calculate acceleration from distance and time, you can only do velocity.
How is acceleration caculated?
Acceleration is the the fluctuation in velocity per unit time.to calculate the acceleration we need the formula : Acceleration = Velocity fluctuations / time taken or Acceleration = Final velocity - Initial velocity / time taken or a = v-u/t
How do you calculate an objects acceleration?
Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)
What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time
Can calculate average acceleration of an obj ect given change in velocity with respect to time?
Acceleration is the derivative of the velocity expression. If you have an equation for velocity, simply take the derivative of it and you will have an equation for the average acceleration.
To calculate acceleration of an object you must find change in?
velocity
How do you calculate acceleration from velocity?
There are 3 formula 1. Final velocity = starting velocity + (acceleration)(time) 2. Final velocity^2 = starting velocity^2 + 2(acceleration)(distance) 3. Distance = (starting velocity)(time) + 1/2(acceleration)(time^2) Use whichever you can use.
What is the only factor needed to calculate change in velocity due to acceleration of gravity (9.8 ms)?
What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 ms?
Why do we calculate acceleration with velocity?
That's because of the way acceleration is defined. It is defined as the rate of change of velocity (change of velocity / time, or in the more general case, dv/dt).
