The time it will take if a car change the velocity from 36m/s to 28m/s with an acceleration of -2.0m/s² is 4s.
<h3>How to calculate deceleration?</h3>
Deceleration is the amount by which a speed or velocity decreases (and so a scalar quantity or a vector quantity).
The deceleration of a body can be calculated using the following formula:
-a = (v - u)/t
Where;
- -a = deceleration
- v = final velocity
- u = initial velocity
- t = time in seconds
-2 = (28 - 36)/t
-2t = -8
t = 4s
Therefore, the time it will take if a car change the velocity from 36m/s to 28m/s with an acceleration of -2.0m/s² is 4s.

Answer:
so his far point according to this pair of glass is 200 cm
Explanation:
power of old pair of corrective glasses is given as
now we have
now we know that for normal vision the maximum distance of vision is for infinite distance
so by lens formula we have
so his far point according to this pair of glass is 200 cm
not enough information is given to determine the velocity of the object at time to=0.00s
