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

Step 1

Given:

Accelerating rate *(a)* = 25 m/s^{2}.

Final velocity *(v)* = 550 m/s.

Initial velocity *(u)* = 0 m/s.

Step 2

The first equation of kinematic is,

where,

*v* = final velocity.

*u* = initial velocity.

*a* = acceleration.

*t* = time.

Step 3

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