A fox is 3.2 m from a 0.5 m tall wall. If it leaps from the ground towards the wall with an initial velocity of 12.0 m/s at an angle of 18.9° above the horizontal, how high off the ground will the fox be when it reaches the wall?

0.7 m.

Explanation:

We are given that

Initial velocity of fox,v=12 m/s

Distance of fox from the ball=3.2 m

Horizontal component of velocity=

Vertical component of velocity=

Time taken by fox to travel in horizontal direction=

Time taken by box to the wall=0.28 s

Formula:

Where

Using the formula

Takine g negative because fox going against to gravity.

Hence, the fox will reach upto height 0.7 m when it reaches the wall

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.
