Answer:
<h2>0.67 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>0.67 m/s²</h3>

Answer:
Time = 4.1 s
Explanation:
Momentum = mv = (12000)(4.25) = 51000 kg m/s
Momentum = Impulse (mv = ft) so
51000 = (9200)t
t = (51000)/(9200) = 5.54 seconds
Impulse of the current and the engine must equal so (ft = ft)
51000 = (12500)t
t = (51000)/(12500) = 4.08
But accounting for significant figures, time equals 4.1 seconds
Answer:
Acceleration of the plane, a = 5.4 g
Explanation:
It is given that,
Speed of the jet plane, v = 1890 km/h = 525 m/s
Radius of the arc, r = 5.20 km = 5200 m
The plane is moving in the circular path, the centripetal acceleration will act on it. It is given by :
We know that, the value of g is, 
So, the acceleration of the plane is 5.4 g. Hence, this is the required solution.

What is a good communication skill?</h3>
- The sender is the person who is trying to communicate a message.
- The challenge is that since the receiver’s education and experience may be very different from the sender's, words often have different meanings.
- While we may carefully choose the words to speak, words alone represent a small percentage.
- communication is only verbal the most important element of communication
- When encountering a noise, take steps to reduce the distraction.

Explanation:
Using Kinematics,
We have v = u + at.
=> v = (5m/s) + (2.0m/s²)(4.0s)
=> v = 13m/s.
Hence the child's speed is now 13m/s.
