Holden is trying to turn man the velocity of his car, he went 20 meters east, turned around and left 40 meters less, he turned the car one more time, and when 35 meters east, his car was 15 metres from the starting line. this took 5 seconds, what is the car
velocity

3 m/s east

Explanation:

The velocity of the car is given by:

where

d is the displacement

t is the time taken

The displacement of the car does not depend on the path of the car, but just on it the difference between its final position and its starting position, so it is equal to 15 metres east. The time taken is 5 seconds, therefore the velocity is equal to

and the direction is east.

double the distance = divide strength by 4

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.
