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
Answer:
Explanation:
Since,
<h3><u>1 kWh = 1 unit</u></h3>So,
1.6 kWh = 1.6 units
If,
<h3>1 unit = 9p</h3>1.6 units = 9p × 1.6
1.6 units = 14.4p
