QUIZ 4 - MOTION IN TWO DIMENSIONS

[FILL IN THE BLANK] The optimal angle for achieving maximum range in projectile motion is _____ degrees.

[SHORT ANSWER TYPE] Explain how air resistance affects the motion of a projectile. Include its impact on both the distance traveled and the time of flight.

Which of the following factors does NOT affect the range of a projectile?

• Launch angle
• Initial velocity
• Shape of the projectile
• Time of day

If a projectile is launched at an angle of 30 degrees, which of the following statements is true regarding its range compared to a projectile launched at 60 degrees?

• The projectile launched at 30 degrees will travel further.
• The projectile launched at 60 degrees will travel further.
• Both projectiles will travel the same distance.
• It cannot be determined without additional information

A scientist launches a projectile at a 45-degree angle. If she were to increase the angle to 60 degrees while maintaining the same initial velocity, what would likely happen to the projectile's height and range?

• Height increases, range decreases
• Height decreases, range increases
• Both height and range increase
• Both height and range decrease
