A ball is thrown vertically into the air. When it returns after an interval of three seconds, it is caught. Which one of the following statements is true if the acceleration due to gravity is 10 m/s2 and air resistance can be neglected?
The acceleration after it leaves the hand is 10 m/s/s downward.
The acceleration at the top of its flight is 0 m/s/s.
The time taken for the descending motion does not equal the time taken for the ascending motion.
The acceleration at the top of its flight is 10 m/s/s upward.
