The relationship is a velocity-time graph. where velocity=displacement/ time
therefore V=m/s because the S.I unit for displacement and for time is m and s.
V=m/s= m/s

A football is kicked straight up from a height of 5 feet with an initial speed of 55 feet per second. The formula h equals negat
makvit [3.9K]

Answer:

3.53 second

Explanation:

The formula for the height is

h=-16t^{2}+55t+5

When it hits the ground, the height is zero.

So, put h = 0 in the above equation

0=-16t^{2}+55t+5

16t^{2}-55t-5=0

t=\frac{+55\pm \sqrt{55^{2}+4\times 5\times 16}}{2\times 16}

t=\frac{+55\pm 57.84}{2\times 16}

Take positive sign

t = 3.53 second.

Thus, the time taken to hit the ground is 3.53 second.

An egg of mass 0.060 kg is dropped from the top of a building. Just before it reaches the ground, it has a total kinetic energy
3241004551 [841]

The velocity is 14 m/s

The parameters given on the question are

mass= 0.060 kg

kinetic energy= 5.9 joules

K.E= 1/2mv²

5.9= 1/2 × 0.060 × v²

5.9= 0.5 × 0.060v²

5.9= 003v²

v²= 5.9/0.03

v²= 196.66

v= √196.66

v= 14 m/s

Hence the velocity of the egg before it strikes the ground is 14 m/s
