Velocity at time 0 sec = 0m per sec

Velocity at time 3 sec = 45m per sec

Acceleration is 45/3 = 15m per sec if the acceleration is uniform

What is the acceleration experienced by a car that takes 10 seconds to reach 27 meters per seconds from rest?

velocity = acceleration x time 27 = acceleration x 10 acceleration = 2.7 m/sec/sec


If a car starts from rest and travels a distance of 100 meters in 10 seconds what is the car acceleration?

2.0 m/s^2


What is the acceleration of the car during this time?

The acceleration of the car would be determined by dividing the change in velocity by the time taken. If the car started from rest and reached a speed of 30 m/s over 5 seconds, the acceleration would be 6 m/s^2.


What is the acceleration of a car that moves from rest to 15.0 meters per second in 10.0 seconds?

Acceleration = change in speed per unit of time = (15-0)/10 = 1.5 metres/sec2


If a car goes in 6.8 seconds how do you figure out the acceleration?

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.


What has more acceleration a car going from 60 to 65 in 2 seconds or a bike going from rest to 5?

if the bike goes from 0-5 in the same amount of time (2 seconds) then they are accelerating at the same rate.

What is the acceleration of a car traveling from 0 to 60 miles in 4 seconds?

There is no acceleration if the car is travelling at a steady 54,000 miles per hour.


What is the average acceleration of a car that starts at rest and then moves straight ahead reaching 18 meters per second in 12 seconds?

It is accelerating at 1.2m/s per second.


What is the acceleration of the car if the velocity of a car increases by 40 ms in 80 seconds?

The acceleration of the car is 0.5 m/s^2. This is calculated by dividing the change in velocity (40 m/s) by the time taken (80 seconds).
