Answer:
160N
Explanation:
Moments must be conserved - so.
solution solved below
Speedometer
Time = 600 seconds
Given the following data;
Power = 60W
Energy = 36000
To find the time;
Energy = power * time
Substituting into the equation, we have;
36000 = 60 * time
Time = 36000/60
Time = 600 seconds.
Therefore, the bulb was on for 600 seconds.
The rate of change of an object's velocity is called acceleration.
