Answer:
1.984 m/s^2
Explanation:
initial velocity of air craft, u = 0 m/s
final speed of the aircraft, v = 120 km/h
Convert the speed into m/s from km/h
So, v = 120 km/h = 33.33 m/s
distance, s = 280 m
Let a be the acceleration of the aircraft.
Use third equation of motion


a = 1.984 m/s^2
Thus, the acceleration of the aircraft is 1.984 m/s^2.
If,

then, with 3x time t, (suppose, new distance is h)




Therefore, new distance h will be 9 times bigger than distance d.
answer: c
Answer:
it's because some versions have more steps and others have less
Answer:
Explanation:
Acceleration = a change in velocity / a change in time
Acceleration = ( final velocity - initial velocity) / a change in time
Acceleration = (6m/s - 35 m/s ) / 5 s
= (-29 m/s) /( 5 s)
= - 5.8 m/s^^2
Remember Significant Figures
- 6 m/s^2
P.S I have no idea why the answers say m/s because acceleration is m/s^2.

Answer:
Explanation:
Suppose when bucket is half full it has a mass of 2 m rotating in a circle of radius r
When Bucket is quarter full then it has a mass of m rotating in a circle of radius r.
When an object moves in a circular path then it experiences an inward force which is given by

where v=velocity of bucket
Force in case 2 is given by

Thus
therefore force required in half bucket is more than force required in quarter bucket full.
