negative one mile per second per second
Acceleration = change in velocity/change in time Acceleration = 96 miles per second - 32 miles per second/8 seconds = 8 miles per second per second or, better expressed 8 mi/s^2 ---------------
After 15 seconds, the train's speed would be 7.5 miles per second. This can be calculated by multiplying the acceleration (0.5 miles per second) by the time (15 seconds).
The acceleration of the car can be calculated using the formula: acceleration = change in velocity / time. In this case, the change in velocity is 20 - 5 = 15 miles per second. So, the acceleration is 15 miles per second / 3 seconds = 5 miles per second squared.
-66.667 miles per second squared
A gain of 2 miles per second squared
20 miles per second / 10 seconds = 2 miles per second ^ 2
To calculate acceleration in miles per hour per second, first convert the acceleration from 0 to 60 mph in 3 seconds to miles per hour. 60 mph / 3 sec = 20 mph/sec. So, the acceleration in miles per hour per second is 20 mph/sec.
-6.667 miles per second squared
3 / 12 = 0.25 miles/second2.
To find the distance traveled, we can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. The initial velocity is 75 miles per second, the final velocity is 145 miles per second, and the time is 15 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time. Plug in the values to find the acceleration and then calculate the distance traveled in 15 seconds.
Acceleration = (change in speed) divided by (time for the change)Acceleration = (25 - 0)/(3) = 81/3 miles per second2Don't try this at home. That acceleration is about 1,368 G's. You can not survive it!
So acceleration is an increase of speed every second. The increase of speed was 9miles/sec and this was over 3 seconds. Therefore there was an acceleration of 3 miles/second every second i.e. 3m/s2
