Question

The vertical velocity of a projectile launch at 35 degree : O continuously decreases O continuously increases O sometimes decreases and sometimes increases O is zero O stays constant.

Answer 1

Answer:Sometime decreases and sometime increases.

Explanation:

Given

Projectile is launched at $35 ^{\circ}$

so horizontal velocity=ucos35

vertical velocity=usin35

since gravity acts in the vertical direction, therefore, it affects only the vertical component of the projectile.

So Vertical velocity first decrease up to maximum height and then starts to increase.
