Sandra's target heart rate zone is 135bpm—172bpm. marissa's target heart rate zone is 143bpm—176bpm. they stop playing basketball and take their pulse, and both count the heart rate at 144bpm. if they decrease their heart rates by 20bpm, who will be in her thr zone?

Neither Sandra nor Marissa will be in her THR zone.

Explanation:

1) Actual pulse of both Sandra and Marissa : 144 bpm

2) Decrease of 20 bpm ⇒ 144 bpm - 20 bpm = 124 bpm

3) Sandra's TRH is in the range 135 - 172 bpm.

Since 124 < 135, she will be below the range.

4) Marissa's TRH range is 143 - 176 bpm.

Since, 124 < 143, she is below the range

In conlusion, neither Sandra nor Marissa will be in her THR zone.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
