Learning Task 3. Problem Solving
Now let us try to solve several problems on projectile.
You need to apply the concepts learned from the previous discussion
1. John kicks a soccer ball 20m/s at an angle of 25 degrees above the
horizontal. What is the horizontal velocity at the peak?
A. Given: horizontal Velocity= 20 m/s
Angle cos 25 degrees= 0.906
B. Required: Horizontal Velocity=?
Vx=?
C. Formula:
D. Solution:
E Final answer:
2. A ball thrown vertically upward reaches a maximum height of 30 meters
above the surface. At its maximum height, the speed of the ball is:
C. 9.8 m/s D. 24 m/s
