Julie is walking around a track at a 2m/s for some exercise. she then decides to start jogging so she accelerates at a rate of 0.5m/s² for 3 seconds. how far did julie travel from the time she started to accelerate to the end of the 3 seconds?

The distance is 8.25 m.

Explanation:

Given  that,

Speed = 2 m/s

Acceleration = 0.5 m/s^2

Time = 3 sec

We need to calculate the distance

Using equation of motion

Where, u = initial velocity

a = acceleration

t = time

Put the value in the equation

Hence, The distance is 8.25 m.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
