A jogger with a constant velocity of 4 m/s runs by a stationary dog. One second after passing the dog, the dog decides to chase the jogger. The dog accelerates from rest at 1.5 m/s^2. (Hint at the end of review packet) a. How long does it take the dog to catch the jogger?
b. How far away from the spot where the dog was sitting has the jogger gone when she is caught by the dog?

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
