Answer:
is the initial velocity of tossing the apple.
the apple should be tossed after
Explanation:
Given:
- velocity of arrow in projectile,
- angle of projectile from the horizontal,
- distance of the point of tossing up of an apple,
<u>Now the horizontal component of velocity:</u>
<u>The vertical component of the velocity:</u>
<u>Time taken by the projectile to travel the distance of 30 m:</u>
<u>Vertical position of the projectile at this time:</u>
<u>Now this height should be the maximum height of the tossed apple where its velocity becomes zero.</u>
is the initial velocity of tossing the apple.
<u>Time taken to reach this height:</u>
<u>We observe that </u><u> hence the time after the launch of the projectile after which the apple should be tossed is:</u>
