Answer:
Cannonball b spends more time in the air than cannonball a.
Explanation:
Starting with the definition of acceleration, we have that:
Since both cannonballs will stop in their maximum height, their final velocity is zero. And since the acceleration in the y-axis is g, we have:
Now, this time interval is from the moment the cannonballs are launched to the moment of their maximum height, exactly the half of their time in the air. So their flying time t_f is (the minus sign is ignored since we are interested in the magnitudes only):
Then, we can see that the time the cannonballs spend in the air is proportional to the vertical component of the initial velocity. And we know that:
Finally, since and
, we can conclude that:
In words, the cannonball b spends more time in the air than cannonball a.
Answer:
<h3>The answer is 12 m/s²</h3>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>12 m/s²</h3>Hope this helps you
