Well, isn't that just a happy little question! To find the acceleration between 20 seconds and 30 seconds, you would need to calculate the change in velocity during that time interval and divide it by the time taken. Remember, acceleration is how quickly an object's velocity is changing over time. Just like adding a touch of bright color to a painting, understanding acceleration can add a beautiful depth to your knowledge of motion.
Acceleration = (change in speed) / (time interval)= (50 - 30) mph / 20 sec = (20 mi/hr) (1/3,600 hr/sec) (5,280 ft/mi) / (20 sec)= (20 x 5,280) / (3,600 x 20) (mi - hr - ft / hr - sec - mi - sec)= 1.4667 ft/sec2 (rounded, repeating)
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
25 is exactly between 20 and 30.
1 min = 60 sec 30 min = 1800 sec
Probably 'between 20 and 30.'
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 20+10 = 30 miles/sec, the initial velocity is 20 miles/sec, and the time is 30 seconds. So, the acceleration of the car is (30 - 20) / 30 = 0.33 miles/sec^2.
Acceleration = (change in speed) / (time interval)= (50 - 30) mph / 20 sec = (20 mi/hr) (1/3,600 hr/sec) (5,280 ft/mi) / (20 sec)= (20 x 5,280) / (3,600 x 20) (mi - hr - ft / hr - sec - mi - sec)= 1.4667 ft/sec2 (rounded, repeating)

The car's acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values, we get: (30 m/s - 20 m/s) / 10 sec = 1 m/s^2. The car's acceleration is 1 meter per second squared.
15sec * * * * * The question is incorrect and so got a wrong answer. Acceleration cannot be measured in m sec but m sec-2. The previous answerer, assumed that the questioner had meant velocity, not acceleration. If the velocity had been 2 m sec-1 then the time would have been 15 seconds. But it was not even m sec-1! It seemed the units were wrong. If you assume that acceleration = 2 m sec-2 then t2 = 2s/a = 2*30/2 = 30 and so t = sqrt(30) seconds = 5.48 seconds (approx)
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2

25 is a perfect square occurring between 20 and 30.
Acceleration = (force)/(mass)For the first object, A = 20/10 = 2 m/s2For the second object, A = 30/18 = 12/3 m/s2The acceleration of the first object is 20% greaterthan the acceleration of the second one.
