Week 7 - Height, angle and velocity of release

Question 1

What will happen to the vertical and horizontal range if release velocity is increased and why

Answer 1

Both horizontal and vertical range will be increased due to increased time in air.

Question 2

Define projection angle

Answer 2

The angle formed between the direction at which a body is projected and the horizontal

Question 3

What is the optimum release angle for vertical displacement

Answer 3

75 degrees

Question 4

What is the optimum release angle for horizontal displacement

Answer 4

45 degrees

Question 5

Explain relative projection height

Answer 5

Difference between height object is initially projected and the height at which it lands

e.g. ball thrown at 1.5m to a ledge of 3m, the relative projection height would be -1.5m. 1.5 - 3 = -1.5.

Question 6

What is the optimal angle for horizontal range with a throw (greater height of release)

Answer 6

< 45 degrees

Question 7

What is the optimal angle for horizontal range with a kick (low horizontal height)

Answer 7

45 degrees
