suppose you push a hockey puck of mass m across frictionless ice for a time 1.0 s, starting from rest, giving the puck speed v a

saul85 [17]

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.

 I hope this is understandable and if my answer helped you please can you give me a brainliest its will really help me and thank you have a nice day!!

An ice skating competition features 8 skaters. How many different ways can the skaters finish the competition? how many differen

yan [13]

The number of ways the skaters can finish the competition is 40,320 ways

The different ways 3 of the skaters finish first, second and third is 56 ways

Given the following

Number of skaters featured = 8 skaters

If the skaters finish the competition, the number of different ways the skaters finish the competition is expressed as:

8! = 8*7*6*5*4*3*2

8! = 56*30*24

8! = 40,320.

The number of ways the skaters can finish the competition is 40,320 ways

If 3 of the skaters finish first, second and third, the number of ways this can be done is given as:

8C3 = 8!/(8-3)!3!

8C3 = 8!/5!3!

8C3 = 8*7*6*5!/5!3!

8C3 = 56 ways

Hence the different ways 3 of the skaters finish first, second and third is 56 ways
