Question

A projectile follows a straight-line path instead of a parabolic trajectory. Which could be the launch angle? would it be 90 or 45 or 3o??

Answer 1

projectile can only follow the straight line path when it is launched upward straightly so the correct option is 90 degree with respect to horizontal x -axis ..:)

Answer 2

90 degree

Step-by-step explanation:

For the horizontal projection or the vertical projection, the path traversed by the projectile is a straight line .

So the angle of projection is 0 degree or 90 degree.

In this condition the motion is in one dimension. If the angle of projection is any arbitrary angle except 0 degree or 90 degree, the motion of the projectile is parabolic.
