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.

Answer:
1500 N
Explanation:
Weight = mg = 150 kg * 10 m/s^2
Weight = 1500 N
This is the description of a creative idea:
A social network platform where people can list their musical interests and select their zone to find groups to go to concerts or festivals together when none of your friends have the same musical interest as you.
<h3>What are creative ideas?</h3>
Creative ideas are ideas that a person has that come from creativity, where imagination takes an important place.
A creative idea can solve a problem because it is thought specially to solve a specific situation. For example, in the idea described before, the problem is that a person might not have someone to go to a concert or festival and the social network platform can help this person find a group of people to go with.
