A.hyperbolic

B.parabolic

C.linear

D.exponential

5)When the range of a projectile (ground launch) is zero ?

A)at launch angle 90 or 0 degrees

B)At launch angle of 90 degrees

C)it is never 0

D)at launch angle of 0 degrees

6)If a projectile is on ascend, what is the angle between its velocity and tangential component of acceleration ?

A)180 degrees

B)No angle as tangential acceleration is zero

C)90 degrees

D)0 degrees

7)If a projectile is on descend, what is the angle between its velocity and tangential component of acceleration ?

A)180 degrees

B)0 degrees

C)No angle as tangential acceleration is zero

D)90 degrees

7)If a projectile is on descend, what is the angle between its velocity and tangential component of acceleration ?
