If a roller coaster goes from zero to 80 miles per hour in 1.8 seconds what is its acceleration in miles per hour per second to the nearest tenth?

It goes from 0 mph to 80 mph in 1.8 seconds Acceleration = change in speed/time taken = (80 - 0)/1.8 mph per second = 44.4 mph per sec


What is the velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?

the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph

How long would it take a car to accelerate from 10 MPH to 75 MPH if its acceleration is 20 MPHs?

Acceleration = Change in speed/Time Time = Change in Speed/Acceleration = 65mph/20mph per s = 65/20 seconds = 3.25 seconds

What is the average acceleration of a car that goes from rest to 60 mph in 8 seconds?

The car accelerates an average of 7.5 mph per second. It increases its speed 7.5 mph for every second that it accelerates. The car accelerated from zero to 60 mph in 8 seconds. If we wish to find out how fast it accelerated, we need to divide its acceleration (final speed minus initial speed) by the amount of time that it took to get going that fast. In this case, 60 divided by 8 equals the answer 7.5 mph/sec.


A motorcycle can accelerate from 0 to 60 in 3 seconds what is its acceleration in miles per hour per second?

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.


An object with constant velocity has positive acceleration?

Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.
