Aposition-time graph is shown below (attached):

which statement accurately describes the velocity of the object in the graph above over the six seconds?

the object moves forward at 5 m/s, stops, and then changes velocity.

the object moves backward, stops, and then continues forward at 5 m/s.

the object is at rest for 2 seconds and then moves at forward at 5 m/s.

the object stops and then returns to its original position and velocity.

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) determine the magnitude and direction of projectile velocity at t= 1.3s b) determine the magnitude and direction of projectile acceleration at t=1.3s

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
