Answer: Twice the previous time would be taken to reach the same speed v with the puck of mass 2m.
Explanation:
Let a Force pushes the hockey puck of mass m.
Then acceleration, a= \frac{F}{m}a=mF
From the equation of motion,
\begin{gathered}\➪ v=u+at\\ v=0+\frac{F}{m}\Delta t\end{gathered}⇒v=u+atv=0+mFΔt ......(1)
In the second case, when mass is 2m, then acceleration,
a'=\frac{F}{2m}a′=2mF
and t' is the time taken.
The final speed is v,
\begin{gathered}\➪ v=0+ a't'\\ \➪ \frac {F}{m}\Delta t=\frac{F}{2m}t'\\ \➪ t'= 2\Delta t\end{gathered}⇒v=0+a′t′⇒mFΔt=2mFt′⇒t′=2Δt using equation (1)
Hence, it would take two times the previous amount of time to push the pluck of double mass.

The percentage increase of the change in price is gotten as; 48%
<h3>How to calculate percentage price increase?</h3>
We are given;
Old Cost Price = $20
New Cost Price = $9.60
Thus, the increase in price is;
29.60 - 20 = $9.60
The percentage increase is;
Percent increase = (29.60 - 20)/20 * 100%
Percentage Increase = 9.60/20 * 100%
Percentage Increase = 0.48 * 100% = 48%
Complete Question is;
The last time i bought this product , it cost $20.00 but it looks like it cost 29. 60 today? What is the percentage increase?
