30 m/s
Explanation:
Velocity is
since we know that the initial velocity is 0, and the acceleration is
then we also know that time is 3 seconds it follows that: 
Answer:
Given the point of maximun electric power of the hair dryer 1500 (w); The circuit breaker won´t trip at all
Explanation:
The most simplyfied relation between power, voltage and current is:
Electric power (in watts) =Voltage (in volts) * current (in ampers)
In the case of P= 1500 (w) and V= 120 (v) we have:
I = 1500/120 (a) = 12,65 (a)
This value is far away of 20 (a) (the nominal trip current
