Activity 4: Projectile Launched at an Angle How about when a projectile is launched at an angle? Will be the horizontal velocity will be the same as the projectile launched horizontally? If not, how these two differ?
A soccer ball is kicked at ground level with a speed of 41.6m / s at an angle of 45^ prime prime to the horizontal. For such an initial velocity, the object would initially be moving 29.4 m / s vertically and 29.4m / s horizontally. These x- and y- initial velocity values will be discussed in more detail in the next module.
Guide Questions:
1. How does horizontal velocity differ from vertical velocity?
2. Based on the table and the graph, what did you observe?

Answer:
1. Well they differ in how long and how tall is the ball kicked.
2. Base on what I observed in the graph the vertical velocity changes ( increases then decreases) while the horizontal velocity remains constant.
Os 29.40m/s
1s. 19.60m/s
2s. 9.80m/s
3s. 0m/s
4s. -9.8m/s
5s. -19.60m/s
6s. -29.40m/s
v = 29.40 m/s
1s: h = 29.40 m/s
v = 19.60 m/s
2s: h = 29.40 m/s
v = 9.80 m/s
3s: h = 29.40 m/s
v = 29.40 m/s
4s: h = 29.40 m/s
v= 9.80 m/s
5s: h= 29.40 m/s
v = 19.60 m/s
6s: h= 29.40 m/s
v = 29.40 m/s
