Answer:
<h2>450 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 250 × 1.8
We have the final answer as
<h3>450 N</h3>
Hope this helps you
Answers with explanation
1)
Transmission
If all the light passes through a medium without any absorption then transmittance is 100%.
2)
Refraction
Refraction is the bending of a wave when it enters a medium where its speed is different and rays are again refracted when they leave that medium,
3)
Reflection
Reflected rays don't pass through the medium instead rays bounces off an object at an angle.

Of the cliff?
Projectile motion
In the problem we are asked to find a height of certain cliff when a motorcycle stunt driver zoom out horizontally at the end the cliff at an initial velocity. So we will use one of the kinematics equation for projectile motion,
y
=
v
o
y
t
+

2
g
t
where
v
o
y
is just equal to zero since we can assume that the driver zooms out horizontally,
g
=

and
t
is time after
