Hello I need help with questions 18-22. If you could provide feedback with the best of your biomechanics and physics ability that would be great. Need back asap!!

1 point An object at point A (2,2) moves to point B (6,7) over a 0.4 second period. What is the overall velocity (in m/s) of the object? (Express your answer to one decimal place). Type your answer. 19 1 point What is the takeoff velocity (in m/s) of an NFL athlete completing a max vertical jump test during the combine if their toes touched the ground 0.8 seconds after their toes left the ground? (Express you answer to two decimal places). Type your answer. 20 1 point At take off, the horizontal and vertical velocity's of a high jumper are 1.6 and 5.4 m/s, respectively. What is the resultant velocity (in m/s) at takeoff? (Express your answer in m/s to one decimal place) Type your answer.. 21 1 point At take off, the horizontal and vertical velocity's of a pole vaulter are 1.2 and 4.6 m/s, respectively. What is the take-off angle from the right horizontal? (Express your answer in degrees to one decimal place) Type your answer.. 22 1 point In tracking the position of an object over time, the steepness of a position-time curve indicates: the slope does not provide enough information the acceleration of the object what direction the object is moving the velocity of the moving object
