A)Determine the maximum height reached by the projectile.B) Determine the total time in the air. C)Determine the total horizontal distance covered (that is, the range). D)Determine the speed of the projectile 1.70 s after firing.

Solutions

Expert Solution

Given initial velocity ,

A)Determine the maximum height reached by the projectile

Use Formula

ANSWER:

=====================

B) Determine the total time in the air

Use Formula

ANSWER:

========================

C)Determine the total horizontal distance covered (that is, the range)

Use Formula

ANSWER:

=====================

D)Determine the speed of the projectile 1.70 s after firing.

Initial velocity can be split into its horizontal and vertical components

Since there is no acceleration in horizontal direction , remains same

First find vertical velocity after 1.7 s

Use formula

------------
