Two balls are kicked with the same initial speeds. ball a was kicked at the angle 20° above horizontal and ball b was kicked at the angle 75° above horizontal. what ball will have bigger speed at the highest point of their trajectory? (section 4.3) ball a ball b impossible to answer without knowing their actual initial speeds. they will have the same speeds

Ball A

Solution:

According to the question:

Two balls A and B are kicked at angle and respectively.

The component of the velocity that provides the ball with the forward movement is the horizontal component, i.e., cosine of the angle.

Since, cos is greater than cos and thus Ball A will have more speed than ball B at the top most point of the trajectory.

the inner core.

good luck: )
