8 episodes. Count it 2 by 2 until you get 16. It would be (2) (8) times.
60 ÷ h = y (or:how much he earned in one hour)
Answer:
25.92 foot strides
Step-by-step explanation:
The man will take 120/5 = 24 five foot stride to cover the initial 120 foot advantage of the child.
Within this time, the child would have covered an additional 24/5 x 2 = 9.6 extra foot stride.
Within this 9.6 food stride of the child, the man will have to take an additional 9.6/5= 1.96 strides.
Total foot stride by the man will be 24 + 1.96 = 25.92 foot strides.
Answer:
Both boxes have the same amount of work applied to them. The smaller box will get to the end first.
Step-by-step explanation:
For the 400 kg box, we can say,
force = 1 newton
force = mass*acceleration
1 = 400*acceleration
acceleration = 1/400 meters per second^2
acceleration = 0.0025 meters per second^2
Each second, the larger box's velocity is increasing by 0.0025 meters per second.
While the smaller box would have an acceleration of...
force = 1 newton
force = mass*acceleration
1 = 200*acceleration
acceleration = 1/200 meters per second^2
acceleration = 0.005 meters per second^2
Which is twice as much as the larger box.
Put simply: if the force applied is the same for the two boxes, then the smaller box will have larger acceleration. This is because more force is needed to push on the larger mass.
Because the smaller box has more acceleration, it will naturally travel faster compared to the larger box. Therefore, the smaller box reaches the goal line faster.
