M6 - Projectiles

Question 1

When creating a suvat, what does u, v and a equal for horizontal motion?

Answer 1

u = u cosx
v = u cosx (same as u)
a = 0

Question 2

When creating a suvat, what does u and a equal for vertical motion?

Answer 2

u = u sinx
a = -9.8

Question 3

What do you need to if the question involves vectors?

Answer 3

• Turn vectors into horizontal and vertical components
• Complete suvat on both horizontal and vertical components
• Turn solutions back into vectors

Question 4

How can you find distance at time T?

Answer 4

• Find horizontal S
• Find vertical S
• Write components as a vector
• Find magnitude of the vector

Question 5

How can you find speed at time T?

Answer 5

• Find horizontal V
• Fins vertical V
• Write components as a vector
• Find magnitude of the vector
