A ball of mass 160 g is thrown vertically upwards with an initial speed of 8 m/s. What is its kinetic energy when it just starts going up? Can you predict the maximum CA height it will reach? (Hint: At the highest point, all of its energy will be potential energy, the potential energy should equal the initial kinetic energy according to the principle of conservation of energy.) [Ans: initial KE= 5.12 J; maximum height the ball will reach = 3.2 m
can u give me a pic of solution
