Question

7. A body is projected at an angle 30° to the
horizontal with a speed of 30 ms-l. The angle
made by the velocity vector with the horizo-
ntal after 1.5 s is
(g=10 ms )​

Answer 1

Answer: zero

Explanation:

If we calculate the vertical component of velocity after 1.5 seconds we get zero which conclude that the particle has reached the highest point at that time. the only velocity acting at highest point is velocity along a horizontal component so the angle made with the initial horizontal component is zero
