It will be necessary for beginners to perform a routine of 3 sets to 10 repetitions. Rest one day. In the third week you can perform 4 sets to 25 repetitions, resting only one day. This will improve the strength in the arms considerably.

For the legs should stimulate the muscle of the quadriceps, should perform an exercise known as squat, to perform it should be lowered with your back straight until the knees form an angle of 90 degrees, for beginners should perform 3 sets of 15 repetitions a day, resting only one day.

Hooke’s Law Worksheet #1
dimaraw [331]

1. F = 0.25N

2. k = 80 N/m

3. x = 0.2m

4. a = 1m/s²

5. x = 42.6m

<u>Explanation:</u>

1. F = kx

  F = 2.5 X 0.1

  F = 0.25N

2. x = 0.25m

   F = 20 N

   F = kx

   20 = k X 0.25

   k = 80 N/m

3. k = 3500 N/m

   F = 700 N

   x = ?

   700 = 3500 x

   x = 0.2m

4. m = 20kg

   k = 244 N/m

   x = 0.1m

   F = 20N

   a = ?

   F = ma

   20 = 20 a

    a = 1m/s²

5. k = 2.3 N/m

   m = 10kg

   x = ?

   F = kx

   10 X 9.8 = 2.3 x

    x = 42.6m
