Calculate its average speed in meters per second
Answer:
5.77 m/s
Explanation:
Speed= Distance/Time
Distance= 40+ half of 40= 40+20= 60 m
Time= 8.8+1.6=10.4 s
Average speed= 60/10.4=5.769230769 m/s
Approximately, the average speed is 5.77 m/s
Answer:
v= 0.2 m/s
Explanation:
Given that
m₁ = 50 kg
m₂ = 100 g = 0.1 kg
u =10 0 m/s
If there is no any external force on the system then the total linear momentum of the system will be conserve.
Initial linear momentum = Final momentum
m₁u₁ + m₂ u₂ =m₂ v₂ +m₁v₁
50 x 0 + 0.1 x 100 = 50 v + 0
0+ 10 = 50 v

v= 0.2 m/s
Therefore the recoil speed will be 0.2 m/s.

It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. If you are <span>presented with several long cylinders made of different materials, the one that are likely to be good conductors of electric current are aluminum and copper. Hope this helps.</span>
