A ball is thrown w a speed of 30m/s at an angle of 10. When is the vertical component of the velocity equal to zero

Now the vertical velocity of the ball thrown at an angle 10° is given as

Voy (initial vertical velocity) = 30m/s x sin 10

Voy (initial vertical velocity) = 5.2m/s

Now the ball is decelerating with an acceleration due to gravity equivalent to 9.8m/s^2.

Let Vy be the final velocity and that is equal to zero in this case.

Now

Vy = Voy - tx9.8

Where t is the time at which the vertical velocity becomes 0.

Substituting the values we get

0 = 5.2-tx9.8

9.8t=5.2

t=0.53 secs
