A because it depends if the athlete is doing an intense workout he/she would need a sports drink to hydrate them selves
Answer:
47628 kg/hr
Explanation:
Total area = 18*20 =360 ft^(2)
no .of snowflakes per minute = 1050*360 =378000
mass of snowflakes per minute = 378000*2.1*10^(-3) =793.8 kg/min
mass accumulated per hour = 793.8kg/min * 60min/hr =47628 kg/hr
Answer:
the vertical acceleration of the case is 1.46 m/s
Explanation:
Given;
mass of the clarinet case, m = 3.07 kg
upward force applied by the man, F = 25.60 N
Apply Newton's second law of motion;
the upward force on the clarinet case = its weight acting downwards + downward force due to its downward accelaration
F = mg + m(-a)
the acceleration is negative due to downward motion from the top of the piano.
F = mg - ma
ma = mg - F

Therefore, the vertical acceleration of the case is 1.46 m/s²
