question

Which one of the following statements is true concerning the motion of an ideal projectile launched at an angle of 45° to the horizontal?

category

physics

options

  1. The horizontal speed decreases on the way up and increases on the way down.
  2. The acceleration vector points opposite to the velocity vector on the way up and in the same direction as the velocity vector on the way down.
  3. The object's total speed increases during the entire flight.
  4. The speed at the top of the trajectory is at its maximum.
  5. The vertical speed increases on the way up and decreases on the way down.
  6. The object's total speed decreases during the entire flight.
  7. The vertical speed decreases on the way up and increases on the way down.
  8. The acceleration vector points in the same direction as the velocity vector on the way up and opposite to the velocity vector on the way down.
  9. The speed at the top of the trajectory is zero.
  10. The object's total speed remains constant during the entire flight.
