An apple falls from an apple tree growing on a 20° slope. The apple hits the ground with an impact velocity of 16.2 m/s straight downward. What is the component of the apple's impact velocity parallel to the surface of the slope? a.5.5 m/s
b.8.7 m/s
c.12 m/s
d.15 m/s
1 answer:
Apple hits the surface with speed 16.2 m/s
The angle made by the apple velocity with normal to the incline surface is given as 20 degree
now the component of velocity which is parallel to the surface and perpendicular to the surface is given as
so here we have
<em>so its velocity along the incline plane will be 5.5 m/s </em>

Answer:
1.44 m/s²
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
This velocity will be the initial velocity of the car when it passes through the first building
The acceleration of the car is 1.44 m/s²
Measure the length of one side and then cube the answer. So if x represents the measurement of one side, x³ will give you the volume.
Since the boot-print was left there nearly 50 years ago, there has been very little wind and very little rain in that area, and plus, there have been very few people or other animals walking around in that spot to disturb it.
