A ball is thrown upwards with a velocity of `29.4 ms^(-1)` in the absence of air resistance.
(i) Mention the direction of the acceleration during the upward motion of the ball.
(ii) What are the velocity and acceleration of the ball at the highest point?
(iii) How much high the ball goes up?
(iv) Find the time taken by the ball to reach the ground. Take g = 9.8 `ms^(-2) `

Explanation

To solve the problem step by step, we will address each part of the question systematically.

### Given Data:
- Initial velocity (u) = 29.4 m/s (upwards)
- Acceleration due to gravity (g) = 9.8 m/s² (downwards)

### (i) Direction of the acceleration during the upward motion of the ball:
The only force acting on the ball is gravity, which acts downwards. Therefore, the direction of the acceleration during the upward motion of the ball is **downwards**.
