Projectile Problems – Type 2: 1. The photograph below shows a basic projectile at several locations on its trajectory.

a) List the location(s) where the vertical component of the velocity would be zero.

b) What is the vertical component of the acceleration at location #3?

c) What is the horizontal acceleration of the projectile?

d) Identify the location where the vertical displacement would be zero.

e) Identify the location with the maximum displacement.

f) Rank each location in terms of the projectile's speed (highest to lowest).

Explanation:

( a ) At top position , vertical component of velocity will be zero .

So answer is position no (3)

b )

At position (3) which is the topmost position , acceleration is acting due to gravity , so it will be downwards.

c )

Horizontal component of acceleration at all points will be zero because gravity acts vertically downwards.

d )

Vertical displacement will be zero at position ( 1 ) and ( 5 )

e )

Displacement is maximum at extreme  position , ie at position ( 5 )

f )

Speed is highest at position (1) and it is lowest at position ( 3 )

From highest to lowest

( 1 ) , ( 2 ) , ( 3 )

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.
