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.

probably not if net force is zero

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
