A Plane has a takeoff speed of 150 m/s and requires 1500m to reach that speed. Determine the acceleration of the plane and the t

luda_lava [24]

1) Acceleration: $7.5 m/s^2$

The motion of the plane is a uniformly accelerated motion, so we can find its acceleration by using the suvat equation

$v^2-u^2=2as$

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the displacement

Here we have

v = 150 m/s is the final velocity of the plane

u = 0 (it starts from rest)

a=?

s = 1500 m is the displacement

Solving for a, we find

$a=\frac{v^2-u^2}{2s}=\frac{150^2-0}{2(1500)}=7.5 m/s^2$

2. Time: 20 s

For this part of the problem, we can use another suvat equation:

$v=u+at$

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time

Here we already know:

v = 150 m/s is the final velocity of the plane

u = 0 (it starts from rest)

$a=7.5 m/s^2$ (found in part 1)

Solving for t, we find the time taken for the plane to reach the final velocity of 150 m/s:

$t=\frac{v-u}{a}=\frac{150-0}{7.5}=20 s$

Sarah, whose mass is 40 kg, is on her way to school after a winter storm when she accidentally slips on a patch of ice whose coe

RideAnS [48]

Sarah's acceleration is $-0.49 m/s^2$

Explanation:

The force of kinetic friction acting on Sarah has a magnitude which is given by:

$F_f = \mu mg$

where

$\mu$ is the coefficient of kinetic friction

m is Sarah's mass

g is the acceleration of gravity

Moreover, according to Newton's second law of motion, we know that the net force on Sarah is equal to its mass times its acceleration:

$F=ma$

where a is the acceleration

Since the force of friction is the only force acting on Sarah, we can say that the net force is equal to the force of friction, therefore:

$F=-\mu mg = ma$

where the negative sign is due to the fact that the force of friction has a direction opposite to the motion of Sarah. Solving for a, we find

$a=-\mu g$

And substituting the following values:

$\mu = 0.05$ (coefficient of friction)

$g=9.81 m/s^2$ (acceleration of gravity)

we find:

$a=-(0.05)(9.81)=-0.49 m/s^2$
