A person’s basal metabolic rate (BMR) is the rate at which energy is expended while resting in a neutrally temperate environment. A typical BMR is 7.00 x 106 J/day. Convert this BMR to units of (a) watts and (b) kilocalories (or Calories) per hour. (c) Suppose a 1.00-kg object’s gravitation potential energy is increased at a rate equal to this typical BMR. Find the rate of change of the object’s height in m/s.
