You said that she's losing 1.9 m/s of her speed every second.
So it'll take
(6 m/s) / (1.9 m/s²) = 3.158 seconds (rounded)
to lose all of her initial speed, and stop.
Answer:
10.2 km
Explanation:
Displacement is the shortest distance from your original position after movement.
Now, the Zambeef delivery truck moves 18 km north and then 10 km east and then 16 km south.
This means that vertically the truck is 2km short of the 18 km he travelled north..
So we can find the displacement using pythagoras theorem..
Let d be the distance from the current position to the initial position.
Thus;
d² = 2² + 10²
d² = 4 + 100
d = √104
d ≈ 10.2 km
I have attached a diagram showing the direction of this displacement
Answer:
(C) Equal to 1.44 watt
Explanation:
We have given energy dissipated through the resistor = 1.44 watt
We have to find the energy supplied by the battery
From Telegence theorem we know that energy dissipated through resistor is equal to the energy supplied
As energy supplied is given as 1.44 watt
So energy supplied by the battery will be equal to 1.44 watt
So option (c) will be correct answer
One-half second after starting from rest, a freely falling object will have a speed of about 5 m/s.
<h3>
What do you mean by falling object?</h3>
Falling things include goods, tools, garbage, and rubbish that are blown, dropped, or displaced from heights.
Physical science research frequently involves the study of gravity. Of course, what makes things fall is the force of gravity. A force of attraction between two objects is constant. This pulling force is similar to the pull of gravity.
given free fall from rest i.e.
initial velocity u=0 m/s
acceleration a = 10m/s2
time t=0.5 seconds
we know final velocity v = u + at = 0 + (10 *0.5) = 5m/s
