Answer:
Kinetic Energy at bottom=2886.5J (when g=9.8m/s²)
<em><u>OR</u></em>
2925J (if g=10m/s²)
Answer:
(d) Less than or equal to the magnitude of vector
Explanation:
The magnitude of any vector is vector sum of magnitude of its component
As magnitude of vector is sum of its component so magnitude of its component never be greater than the magnitude of vector
It can be equal to the magnitude of vector in one case when the magnitude of other component of the vector is zero
So it can be less or equal to the magnitude of vector

Answer:
60 to 80%
Explanation:
For maximum benefit, the heart rates during exercise regimes should be between<u> 60 to 80% </u>of an individual's maximum heart rate.
<em>The maximum heart rate varies from individuals to individuals and largely depends on age. It is calculated by subtracting one's age from 220. For example, a person that is 40 years old would have a maximum heart rate of;</em>
<em> 220 - 40 = 180 beats per minute.</em>
Such a person's heart rates during exercises should be between 108 and 144 beats per minute for maximum benefits.
