Complete Question
The complete question is shown on the first uploaded image
Answer:
a
b
Explanation:
From the question we are told that
The maximum height is H = 2.70
The Range is R = 12.9 m
Generally from projectile motion we have that
Generally from trigonometric identity
So
=>
Also the maximum height is
=>
=>
=>
=>
Dividing equation 2 by (1)
=>
=>
=>
So
From equation 1
=>
Generally the vertical component of the initial velocity is mathematically evaluated as
=>
=>
Generally the time taken is mathematically represented as
=>
=>
Answer:
<h2>400 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 100 × 4
We have the final answer as
<h3>400 J</h3>
Hope this helps you
I think the answer is 8.2 mm
In physics, the term conservation refers to something which doesn't change. This means that the variable in an equation which represents a conserved quantity is constant over time. It has the same value both before and after an event.
