SELF-PACED SELF-PACED PROBLEM 1 PROBLEM 2 Calculate the displacement and A basketball referee tosses velocity at times of (a) 0.500, (b) the ball straight up for the 1.00s, (c) 1.50s, and (d) 2.00s for starting tip-off. At what a ball thrown straight up with an velocity must a basketball initial velocity of 15.0 m/s. player leave the ground to rise 1.55m above the floor in an attempt to get the ball? SELF-PACED SELF-PACED PROBLEM 3 PROBLEM 4 You throw a ball straight up with an initial velocity of 15.0 m/s. It A rock is dropped from a passes a tree branch on the sea cliff, and the sound of it way up at a height of 7.00 m. striking the ocean is heard How much additional time will 3.4 s later. If the speed of pass before the ball passes the sound is 340 m/s, how high tree branch on the way back is the cliff? down
