Can someone please help me solve this? thank you!

The labeled graphs below represent the upward trajectories of 4 bodies, two sliding upwards on frictionless inclines and two in free flight. Note that all 4 bodies reach the same maximum height (9 meters) after traveling from the same initial elevation (0 m) 10 0 1 2 3 456 789 10 11 12 13 14 15 16 Relative horizontal position, x, (m) The initial speed of N is [less than that of R. .The time of travel of Q is les thanthat of P ·The initial speed of Q is greater than that of P . The time of travel of N is equal to that of R . The initial speed of P is less than that of N.

Explanation / Answer

Less than
Equal
Equal
greater than
equal
equal

as max height is same time of flight is same for all 4
