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
Answer:
'16' is the answer.
Step-by-step explanation:
So, 6=x+2 divided by 3. In this case, we can multiply 6 and 3 which makes
18 = x+2. We substract 2 from 18 and the answer is 16. If you don't understand anything, you can ask by leaving a comment below. Thanks.
16+2 = 18/3 = 6
