The speed that the person needs to leave the ground will be 4.32m/s
From the question given,
Height = 95cm
Since the person leave the ground v = 0m/s
acceleration due to gravity g = 9.8m/s²
Using the equation of motion
v² = u² + 2as
a = -g (upward motion)
s = h (distance changes to height)
The equation will become:
0² = u² - 2gh
0² = u² - 2(9.8)(0.95)
u² = 18.62
u = √18.62
u = 4.32
Hence the speed that the person needs to leave the ground will be 4.32m/s

First let us compute for the total growth in population.
Growth = 155 million * 0.01
Growth = 1.55 million
Since there are 12 months in a year, therefore the new
jobs every month should be:
new jobs per month = 1.55 million / 12
<span>new jobs per month = 0.129 million = 129,167 </span>
Answer: 150 joules
Explanation:
Force applied on a block = 25N
Distance moved by block = 6 m
Workdone = ?
Recall that work is done when force is applied on an object over a distance. And it is measured in joules.
I.e Workdone = Force X Distance
= 25N x 6 metres
= 150 joules
Thus, 150 joules of work is done by the applied force.
