After touchdown a fighter jet passes a marker on the runway at an instantaneous speed of 100 m/s and constant negative accelerat

ion of -15 m/s2. After slowing down to 25 m/s, the pilot suddenly goes to full power to provide a new constant acceleration of 35 m/s2 for a "touch and go" takeoff. How far from the original runway marker does the plane achieve its takeoff speed of 170 m/s?

Given that,

Deacelectration = -15 m/s²

Negative sign shows the declaration

Slowly speed = 25 m/s

Acceleration = 35 m/s²

Speed = 170 m/s

We need to calculate the time

Using equation of motion

v=u+at

Where, v = final velocity

u = initial velocity

a = acceleration

t = time

Put the value into the formula

25=0+15\times t

t=\dfrac{25}{15}

t=1.66\ sec

We need to calculate the distance from the original runway

Using equation of motion

s=ut+\dfrac{1}{2}at^2

s=0+\dfrac{1}{2}\times35\times(1.66)^2

s=48.2\ m

Hence, The distance from the original runway is 48.2 m.

if heat energy is transferred from direct contact between a warm and a cold object it has been transferred by what ?
Katarina [22]

When heat energy is transferred from direct contact between a warm and a cold object , it is known as heat transfer by conduction.

In conduction, the heat transfer takes place within an object or between two objects in contact until the temperature becomes uniform. this kind of heat transfer continues until the temperature at two ends between which the heat transfer take place , becomes equal.  Heat transfer takes place from point at high temperature to point at lower temperature.
