Question

Problem 15

Answer 1

Given information

The angle at which the projectile is launched    and its speed is given  .

We have to find how does the horizontal component of its velocity   after launch compare with its horizontal component of velocity  after launch, ignoring air resistance

Step-by-step explanation

Step 1.

In projectile motion, the horizontal component of velocity remains constant as there is no increasing speed in the horizontal path.

Component of velocity in horizontal direction =
