Question

A football player kicked the ball at the speed of 27.0 m/s as shown in the figure. Determine the range and the height achieved by the ball at the given angle. (Assume that the speeds are the same at a different angle.) Questions: 1. What is the distance traveled by the ball at 20°? 2. How would you compare the distance travelled by the ball at angles of 35° to 55°? 3. At what angle of projection is the distance travelled maximum? 4. What is the height achieved by the ball that is projected at an angle of 70°? 5. Compare the height achieved by the ball projected at 35° to 55°.

Objective:
Solve problems for projectiles launched horizontally and at various analan in thn
horizontal to calculate maximum height, range, and overall time
of flight of the projectile.
Procedure:
Complete the table below.
• A football player kicked the ball at a speed of 27.0 m/s as

4. What is the height achieved by the ball that is projected at an angle of 70°?
5. Compare the height achieved by the ball projected at 35° to 55°.
Closure:
Explain the relationship between the angle of projection to the range and height of a projection.

VALUING
Mobile legends, clash of clans, and Minecraft are examples of mobile games that are being
played by children of all ages. There are now more people playing mobile games than playing
sports. Sports will make our body fit and healthy, unlike video games where you will be more
exposed to diseases such as high blood pressure because you will gain weight.
