    for the first two seconds the object is decelerating at about 10ms-2... so could be caused by gravity.

    for the first 0.5 seconds the object is moving upwards, because the velocity is positive. it reaches the highest point at 0.5 seconds then comes down. at 2 seconds it is given a large upwards velocity, perhaps by being hit by a bat or something ?

    then it continues upwards for another half second and reaches the top 2.5 seconds after the beginning.*

    I would add to what the bear had described.

    The ball is thrown upward at 5 m/s at a higher platform (10 m) above the ground.

    At time t = 2.0, the ball hit the hard ground and rebound immediately with an upward speed of 10 m/s but there is a loss of energy.

    The ball continues upward and reaches the peak or top at t = 3.0 s when the speed is zero.
