Answer:
C.
Explanation:
The acceleration of an object can be found using the equation:
where
v is the final velocity
u is the initial velocity
t is the time it takes for the velocity to change from u to v
In this problem:
u = 30 m/s is the initial velocity of Angelica
v = 84 m/s is the final velocity
t is the time
Substituting into the equation, we find the acceleration:
There isn't a direct answer to this, but I can show you!
This is how you group Pennies, Nickels, and Dimes.
1 Penny= 1 cent.
1 Nickel= 5 cents.
1 Dime= 10 cents.
Imagine if there was 5 pennies, 3 dimes, and 8 Nickels.
That might seem like a lot of numbers, but it's pretty simple!
You know how pennies are worth 1 cent? If we had 5 pennies, that would be 5 cents.
1+1+1+1+1=5 cents.
Then, we have 3 dimes. Dimes are each 10 cents.
So, 10x3 (If you know multiplication, if not, you will learn it later) :)
10+10+10= 30 cents.
Now, nickels. We have 8 nickels! Remember, each nickel is 5 cents.
5+5+5+5+5+5+5+5=
40 Nickels.
Now add all of the coins up.
5 cents + 30 cents + 40 cents = 75 cents!
I hope this helped! If you need more help, you can ask me. :)
Answer:
(a) 32.5 kgm/s
(b) 32.5 Ns
(c) 10.8 N
Explanation:
The change in momentum can be calculated from the definition of linear momentum:
Then, the change in momentum of the body is of 32.5 kgm/s (a).
Now, from the impulse-momentum theorem, we know that the change in momentum of a body is equal to the impulse
exerted to it. So, the impulse produced by the force equals 32.5 kgm/s (or 32.5 Ns) (b).
Finally, since we know the value of the impulse and the interval of time, we can easily solve for the magnitude of the force:
It means that the magnitude of the force is of 10.8N (c).
