Answer:
The speed of the bullet is 220.6 m/s.
Explanation:
Given that,
Distance = 64 cm
Angular displacement = 20.3°
Rotational speed = 1165 rev/min
We need to calculate the time
Using formula of angular displacement
Put the value into the formula
We need to calculate the speed of the bullet
Using formula of speed
Put the value into the formula
Hence, The speed of the bullet is 220.6 m/s.
Remark
It's not the number that's the problem. It's the minus sign.
Just use F = m*a to get the numerical answer. F = 51 * 11 = 561 N
Now we come to the hard part. If you learn nothing else in physics, you learn that minus signs are either your best buddy or your worst enemy -- one that you pay a mafia hit man a lot of money to get rid of.
In this case, you better start looking for a guy wearing a white tie.
What you are finding is a force that is acting against the starting block. In order to move forward, you have to push against something to accomplish going forward. That's why the block is there: it absorbs the push and you pop forward. You should draw a diagram of the block so you see how many forces act on it.
Answer: - 561
