Question

A particle is thrown with some initial velocity at an angle alpha to the horizontal.Its velocity when it is at the heighest point

Answer 1

Answer:

Given:

A particle is thrown at an initial velocity "v" at an angle α

To find:

Velocity at the highest point

Concept:

When an object is thrown at an angle, the object undergoes oblique projectile trajectory.

In such a motion, we can divide the initial velocity into 2 components such as :

1. x - component => v cos(α)

2. y - components => v sin(α)

.

At the highest position, y component of velocity becomes zero . The object only has x component of velocity.

So it's velocity remains {v cos(α) }
