Answer:
Step-by-step explanation
The first step you have to get it into this form
a + bx + c
So that would be
3x + 1x + c
we do not know what c is
we have to get x by it self from 3x so first you have to square it now we are at 9x
9x divided by 9 that would leave us with x
so our finished product is x + 1x + c
we have to get x by itself from 1x so we do exactly what we just did 1x divided by 1x would leave us with x
x + x= + x
+ c is the finished product which is your answer

Answer:
<em>The ball's speed will be 10 m/s at t=1.22 seconds</em>
Step-by-step explanation:
The vertical motion of an object is controlled by the force of gravity. This means that there is a non-zero net force acting on the object that makes it accelerate downwards.
If the object is thrown upwards at speed vo, its speed at time t is:
Where g is the acceleration of gravity
Our ball is thrown upwards with v0=22 m/s. We need to calculate the time when its speed is vf=10 m/s.
Solving the above equation for t:
Substituting:
t=1.22 seconds
The ball's speed will be 10 m/s at t=1.22 seconds
