JEE Main 2022 Physics question
A ball is thrown vertically upwards with a velocity of 19.6 from the top of a tower. The ball strikes the ground after 6 s. The height from the ground up to which the ball can rise will be (k/5) m. The value of k is . (use g = 9.8 )
Answer: 392
Solution
The ball rises for 19.6/9.8 = 2 s above the tower, so it takes 4 s to fall from the highest point to the ground. The
