what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)

Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.

Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)

The answer will depend on its acceleration.

To find the average acceleration over the first 5.1 seconds of motion, divide the change in velocity over that time period by the time taken. Calculate the final velocity minus the initial velocity over 5.1 seconds to find the average acceleration.

The horse's average acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values, we get: acceleration = (10 m/s - 0 m/s) / 5 s = 2 m/s^2. Therefore, the horse's average acceleration is 2 m/s^2.

The average acceleration of the cyclist can be calculated using the equation: average acceleration = (final velocity - initial velocity) / time. In this case, the cyclist's initial velocity is 0 m/s, the final velocity is 15 m/s, and the time is 10 seconds. Therefore, the average acceleration is (15 m/s - 0 m/s) / 10 s = 1.5 m/s^2.

The average acceleration during the time interval from 0 to 10 seconds is the change in velocity divided by the time interval. If you provide the initial and final velocities during this time interval, we can calculate the average acceleration for you.

To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.

Average acceleration = (amount of change in speed velocity) / (time for the change) = (30 - 10) / (4) = 5 meters per second2 to the east

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