The force required to slow the truck was -5020 N
Explanation:
First of all, we find the acceleration of the truck, which is given by
where
v is the final velocity
u is the initial velocity
t is the time
For the truck in this problem,
v = 11.5 m/s
u = 21.9 m/s
t = 2.88 s
So the acceleration is
where the negative sign means that this is a deceleration.
Now we can find the force exerted on the truck, which is given by Newton's second law:
where
m = 1390 kg is the mass of the truck
is the acceleration
And substituting,
So the closest answer among the option is -5020 N.

Jupiter because it’s completely gas.
Answer:
Her acceleration is 0 m/s²
Explanation:
We note that the motion of the girl is on a straight road, therefore;
The vertical acceleration (e.g. due to gravity, <em>g)</em> on the horizontal motion = 0
The horizontal acceleration, a = (Change in velocity, Δv)/(Change in time, Δt)
For uniform velocity, the change in velocity, Δv = 0
Therefore, fore any change in time, Δt, we have;
a = Δv/Δt
Her acceleration, a = 0/Δt = 0
Her acceleration, a = 0 m/s²
I would have to say that 'B' and 'D' are both correct.
Increasing the voltage that you're using to operate a circuit
causes the current in the circuit to increase. But current is
just the number of electrons that are flowing through it. So
right there, you have the increase in the number of charges.
Now, every electron that flows through the circuit gives up
some energy on the way. So if there are more electrons
making the trip, then more energy has been put into the circuit.
Jessica, I absolutely love your printing.
I wish I could print so clearly.
Violence and incivility between hospital employees can contribute to turnover of top performers, hinder effective teamwork, and jeopardize the quality of patient care.This is one of the most important reasons why violence and incivility in hospitals should be avoided at any cost so as to spare the employees and patients from harm and discomfort.
