# Question #a7296

##### 1 Answer

#### Explanation:

We know that angular momentum

#vecL=vecrxxvecp#

where#vecp# is linear momentum and#=mvecv#

The velocity of the particle changes continuously due to acceleration due to gravity

Similarly horizontal component of velocity

We know that at maximum height vertical component of velocity is zero.

(Please read initial velocity as

Using the kinematic equation

Now

Inserting calculated values we get
