what is the acceleration of a plane that increases its speed from 800 km/hr in 5 seconds?

Question

what is the acceleration of a plane that increases its speed from 800 km/hr in 5 seconds. give the solution.

Answer 1

If you mean it got up to 800 miles at its total max, then the acceleration rate would be 160miles a second

A=dv/dt//T

A=800/0//5

A=800//5

A=160miles/s

Answer 2

From 800 km/hr to what speed?

If we assume that the plane reached a speed of 800 km/hr from rest in 5 secs, the acceleration is 800 / 5 = 160 km/sec^2

Answer 3

v1= 0
t1= 0
v2= 800km/hr
t2= 5s

Since there are 3,600 seconds in an hour, you take 800km/hr and divide it by 3,600 to get about 0.222km/s. Since acceleration= v/t, 0.222km/s divided by 5s is equal to 0.0444km/s^2.

You could also express this answer in km/hr^2. 800km/hr divided by 0.001389hr (which is equal to 5 seconds) is 576,000 km/hr^2.

You can check your answer by using dimensional analysis and you'll see that the two answers are equal.

You could have just did a=v/t, but then you would get a complicated unit and my AP physics teacher told my class not to do that.

Answer 4

a=60 m/s^2

Answer 5

you can do it by ,
a=dv\dt

or

a=v-u\t
v-800 km\hr
u-o km \hr
t-0.oo13hr

a=615384.61

Answer 6

a = dv/dt
