Acertain car is capable of accelerating at a rate of 0.60 m/s^2. how long does it take for this car to go from a speed of 55mi/h to a speed of 60 mi/h?
i know the answer is 3.7seconds! i am just confused on the steps to get the answer.

This car needs 3.7 seconds to go from a speed of 55 mi/h to a speed of 60 mi/h.

Acceleration is rate of change of velocity.

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem !

Given:

Acceleration = a = 0.60 m/s²

Initial Velocity = u = 55 mi/h = 24,5872 m/s

Final Velocity = v = 60 mi/h = 26,8224 m/s

Unknown:

Time Taken = t = ?

Solution:

Recall the formula for calculating acceleration as mentioned above.

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
