During a takeoff run, an aircraft starts from rest and has a lift-off speed of 120 km/h. a. What minimum constant acceleration d
svp [43]

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

v^{2}=u^{2}+2\times a\times s

33.33^{2}=0^{2}+2\times a\times 280

a = 1.984 m/s^2

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

If you drop an object from rest, the distance it falls is given by (1/2)at2, where a is the acceleration of the object and t is
klio [65]

If,

d \:  =  \:   \frac{1}{2} a {t}^{2}

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

h \:  =  \:   \frac{1}{2} a {(3t)}^{2}

=  \frac{1}{2} a9 {t}^{2}

= 9 \:  \frac{1}{2} a{t}^{2}

= 9d

Therefore, new distance h will be 9 times bigger than distance d.

A car is traveling in a race. The car went from the initial velocity of 35 m/s to the final velocity of 6 m/s in 5 seco
ddd [48]

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.

Anna Litical is practicing a centripetal force demonstration at home. She fills a bucket with water, ties it to a strong rope, a
dlinn [17]

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

F_1=\frac{2mv^2}{r}

where v=velocity of bucket

Force in case 2 is given by

F_2=\frac{mv^2}{r}

Thus F_1=2F_2

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