Question

1.Determine whether the following statements are true, are false or if it depends. Explain why.

a) True or False or It Depends: Assuming a 45 degree launch angle and neglecting drag, the horizontal velocity is constant while the projectile is in motion.

b) True or False or It Depends: Assuming a 45 degree launch angle and including drag, the horizontal velocity is constant while the projectile is in motion.

c) True or False or It Depends: The terminal velocity of an object depends on its initial velocity.

d) True or False or It Depends: The velocity of the projectile is zero when a projectile is at the highest point of its trajectory.

e) True or False or It Depends: The terminal velocity is higher for objects with larger mass.

Explanation / Answer

(a) neglecting drag, Horizontal component of velocity is constant for all angles of projection. so TRUE

(b) when we include drag Horizontal component of velocity is not constant. so FALSE

(c) Terminal velocity depends on the initial velocity so TRUE

(d) only the vertical component of velocity is zero when the projectile is at the highest point of trajectory. so FALSE

(e) Terminal depends on Initial velocity, drag, angle of projection etc Not on Mass so FALSE
