Dogs dream like humans and about similar things. Many people believe that dogs do dream. Most dog owners have noticed that at various times during their sleep, some dogs may quiver, make leg twitches, or may even growl or snap at some sleep-created phantom, giving the impression that they are dreaming about something.
According to Newton's second law. £Fext=m.a
then the acceleration of the second object will be twice as that of the first since the mass of both objects is equal(100kg) and the force F is doubled. Therefore the acceleration of object 2 will be more than that of object 1 (double)
hope this helps.

Answer:
47 m
Explanation:
Data obtained from the question include the following:
Length of dry leg 1 (L1) = 40 m
Length of dry leg 2 (L2) = 25 m
Length of swimming course (L) =..?
The length of the swimming course can be obtained by using pythagoras theory as shown below:
L² = L1² + L2²
L² = 40² + 25²
L² = 1600 + 625
L² = 2225
Take the square root of both side.
L = √2225
L = 47.1 ≈ 47 m
Therefore, the length of the swimming course is approximately 47 m.
