Answer #1

Given launch velocity,

Part A) Max height

Use formula

ANSWER:

Part B) Time of flight

Use formula

ANSWER :

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

Part C) Range

Use formula

ANSWER:

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

Part D)

Given launch velocity,

Vertical launch velocity,

Vertical velocity after 1.30s

Use formula

Horizontal launch velocity,

Horizontal velocity after 1.30s

There is no acceleration in horizontal direction ,so horizontal velocity remains same

Velocity after 1.30s
