Answer:

Maximum height reached is given as H = 5.00 m

Explanation:

As we know that if the ball is projected at some angle with the horizontal then the range of the projectile is given by the formula

R = \frac{v^2 sin2\theta}{g}

here we have

R = 55 m

\theta = 20^o

v = 40 m/s

Now we have

55 = \frac{40^2 sin40}{g}

g = 18.7 m/s^2

now for maximum height we have

H = \frac{v^2sin^2\theta}{2g}

H = \frac{40^2 sin^220}{2(18.7)}

H = 5 m

What is non uniform velocity​
saul85 [17]

Answer:

"Non-uniform velocity" occurs when<em> an object changes its velocity </em>upon motion. This happens when the object either accelerates or decelerates <em>(negative acceleration)</em> in its speed or changes its direction.

Explanation:

"Velocity" refers to<em> speed with a specific direction. </em>

If the velocity is uniform, there's<u> no change in speed and direction</u>. However, if changes occur on either the speed, direction or both, then <em>the velocity becomes </em><u><em>variable or non-uniform.</em></u>

For example, when it comes to a moving car, it is said to be in non-uniform velocity if <em>the distances covered is unequal in relation to the equal intervals of time.</em>
