## How do you find the greatest height reached by the ball?

We know the value of g in SI is 9.8 m/second square. So just for example, if a ball is thrown vertically upwards with 98 m/s velocity, then to reach the maximum height it will take = 98/9.8 =10 seconds.

## What is the height reached by the ball after 1 second?

After 1 second, the height of the ball is 86 feet.

**How do you find the height of a ball after 2 seconds?**

The time to reach its maximum height derives from Vf = Vo – gt or 0 = 64 – 32t making t = 2 seconds. Since it takes the same time to fall back to the ground, the total time from start to finish is 4 seconds. The maximum height reached derives from h = 64(2) – 16(2^2) from which h = 64 ft.

### What will be the height of the ball after 2.5 seconds?

A ball is thrown upward from an initial height of 100 ft with an initial velocity of 80 ft per sec. After 2.5 sec the ball reaches its maximum height of 200 ft. Solution The height is zero when the ball hits the ground.

### What is the initial velocity when the ball is thrown upwards?

The answer came out positive which indicates the initial velocity was upward. The ball is thrown upwards and returns in 6 seconds, so it spends half the time, or 3 seconds, going up, and another 3 seconds coming down. At max height, v = 0. So: = − 4.9 ⋅ ( 3 2) + 29.4 ( 3)

**How do you calculate the height and projection of a ball?**

Calculate: (i) the greatest height reached by the ball, and (ii) the initial velocity of the ball. (Take g = 10ms−2) To calculate height, consider motion of the ball from highest point to the ground To calculate projection velocity, consider motion of the ball from projection to return to the point of projection.

#### Why is the acceleration of the ball negative in the graph?

The acceleration is negative because this acceleration is directing downwards while the ball is moving upward. And because of this negative acceleration, the velocity of the ball is gradually decreasing.

#### What is the maximum height reached by a golf ball?

So the greatest height reached by the ball is of 45 m and the initial velocity of the ball is 30 m/s. Lead the way to more purchases. Create unique paths and experiences to lead prospects to purchases with Customer Journey Builder.
