Question

A projectile is projected in x-y plane with initial velocity of u = (3i + 4j)ms-1.velocity at highest point is............... Ms-1

Answer 1

Answer:

(3i+0j)ms-1

Explanation:

because at highest point y-component of velocity becomes 0 and hence there will no acceleration in X direction the X-component of velocity remains same.

Answer 2

Answer:

3m/s

Explanation:

at highest point v in y-axis is zero

therefore velocity in x-axis is the velocity at highest point

velocity in x-axis=3
