Complete Question
A frog jumps to the left with an average speed of 1.8m/s for 0.55s What was the frog's displacement in meters.
Answer:
The displacement is
Explanation:
From the question we are told that
The average speed is
The negative sign indicates that the frog jumped to the left (negative x-axis )
The time taken is
Generally displacement is mathematically represented as

The velocity of the ball at its maximum height is zero (0).
The given parameters;
- <em>initial vertical velocity of the ball, </em>
<em> = 18.5 m/s</em>
- <em>height of the cliff, h = 25</em>
<em />
In a projectile motion, as the object ascends upwards, its vertical velocity decreases and eventually becomes zero as the object reaches maximum height.
This <em>velocity</em> starts to increase again as the object descends downwards and finally becomes maximum before the object hits the ground.
Thus, we can conclude that the velocity of the ball at its maximum height is zero (0).
