20mps
answer is 20
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.

To find the acceleration, we can use the formula: acceleration = (final speed - initial speed) / time. Mike's car accelerates from 0 mph to 60 mph in 5 seconds, so the acceleration is (60 mph - 0 mph) / 5 seconds = 12 mph per second. Therefore, the acceleration of Mike's car is 12 miles per hour per second.
The force required to accelerate the motorcycle can be calculated using Newton's second law, which states that force equals mass times acceleration. In this case, the force needed would be 1250 N (250 kg * 5 m/s^2).
F = m A = (250) (5) = 1,250 newtons
The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.
The runner's acceleration can be calculated using the formula a = Δv/t, where Δv is the change in velocity (11 m/s - 0 m/s = 11 m/s) and t is the time taken (5 seconds). Therefore, the acceleration is 11 m/s divided by 5 seconds, which equals 2.2 m/s².
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
Please use Newton's Second Law: force = mass x acceleration. Solving for acceleration: acceleration = force / mass. With the units you are using, the answer will be in meters per second squared.
