Choice D. - 23.04 + 124.1 + 34.06
Hope I was able to help! :)
Answer:
-2
Step-by-step explanation:
You would need 6 packages for 27 students because 27 isn't divisible by 5 without a remainder and all students need pencils. So, you would need to bu another package of pencils.
K=4.5
X multiplied by 4.5 equals y, meaning the constant of proportionality is 4.5
You need to divide this problem into two parts
first part is when it was accelerating.. that time use the equation of motion and calculate what is the total angle covered and hence you get the number of revolutions
then find the time of acceleration..so you ll understand for how much did you do the above calculation
for the rest of the time, the speed is constant (final angular speed).. so now you just use
w= theta/ time.. and get theta and again calculate the number of revolutions!
