Asked Feb 15, 2020
If an object is accelerating at a rate of 25 m/s2, how long (in seconds) will it take to reach a speed of 550 m/s? (Assume an initial velocity of zero.)
Group of answer choices

Expert Answer

Step 1


Accelerating rate (a) = 25 m/s2.

Final velocity (v) = 550 m/s.

Initial velocity (u) = 0 m/s.


Step 2

The first equation of kinematic is,

v = final velocity.

u = initial velocity.

a = acceleration.

t = time.

Step 3

Time taken by an object to reach at 550 m/s,
