A dockworker applies a constant horizontal force of 73.0 N to a block of ice on a smooth horizontal floor. The frictional force
is negligible. The block starts from rest and moves a distance 13.0 m in a time 4.50 s.(a)What is the mass of the block of ice?(b)If the worker stops pushing at the end of 4.50 s, how far does the block move in the next 4.20s ? -

Answer:
v = 4.18 m/s
Explanation:
given,
frequency of the alarm = 872.10 Hz
after passing car frequency she hear = 851.10 Hz
Speed of sound = 343 m/s
speed of the jogger = ?
speed of the
v_o = 872.1 - 10.5
The speed of jogger
v = 4.18 m/s
Answer:
-8.56V
Explanation:
Our values are given by,
e = 6.04 V
Φ = 30.3
VC = 5.32
We can calculate the voltage across the circuit with the emf formula, that is,
Now, Using Kirchoff Voltage Law,
Finally we have the potential difference across the inductor.
