Question

1. 1. A baseball is thrown horizontally at a speed of 43 m/s. When it reaches home plate, what is the horizontal component of its velocity?

2. A baseball is thrown with 33.9 m/s at an angle of 35.4 degree above the horizontal. It is caught at the same height by another player a distance of 38 yards away. What is the speed of the ball, just before it is caught? 1. A baseball is thrown horizontally at a speed of 43 m/s. When it reaches home plate, what is the horizontal component of its velocity? 1.

Explanation / Answer

1) the horizontal component of velocity does not change at all because there is no force acting in the horizontal direction and hence no acceleration. so horizontal component of velocity is 43m/s.

2)the horizontal compoment of velocity does not change due to the above reason.

the magnitude of the vertical component is also the same because it drops down to the same height above the ground so the total speed just before catching is the same but the direction of the vertical component of velocity is reversed hence the velocity is 33.9 m/s at an angle of 35.4 degree below the horizontal
