Tossed Ball

Printer Friendly Version
A ball tossed upward has initial velocity components 30 m/sec vertical, and 5 m/sec horizontal.
 
Pythagorean Theorem resultant velocity
The position of the ball is shown at 1-second intervals. Air resistance is negligible and g = 10 m/sec2.
 
Refer to the following information for the next seven questions.

Fill in the boxes, writing in the values of velocity components ascending, and your calculated resultant velocities descending







Tossed ball
Refer to the following information for the next three questions.

A child tosses a second ball along the dashed path. The velocity vector, complete with its horizontal and vertical components, is shown at position A.  Mentally "sketch" the appropriate velocity vectors with appropriate components for positions B and C.
 
Since there is no acceleration in the horizontal direction, how does the horizontal component of velocity compare for positions A, B, and C? 

What is the value of the vertical component of velocity at position B? 

How does the vertical component of velocity at position C compare with that of position A?
