A ball is thrown from a point 6 metres above the ground. The graph shows the height of the ball above the ground in metres. Estimate the speed of the ball. in m/s after 1 second You must show your working Time (Seconds) 4 5 square 3

## Step 1: The problem does not provide a graph, but it does tell us that the ball is thrown from a height of 6 meters. We can assume that the ball is thrown vertically upward. ## Step 2: The speed of the ball after 1 second can be estimated using the formula for the velocity of an object under the influence of gravity. This formula is given by:### where:- is the final velocity (which we are trying to find),- is the initial velocity (which we don't know),- is the acceleration due to gravity (approximately ), and- is the time (1 second in this case).## Step 3: Since we don't know the initial velocity of the ball, we need to make an assumption to estimate it. A reasonable assumption would be that the ball was thrown with enough velocity to reach its maximum height in about 1 second. This would mean that the initial velocity was approximately equal to the acceleration due to gravity, or .## Step 4: Substituting the values into the formula, we get:###
