8. A car starts from rest and accelerates at 5.5ms in an easterly direction. Calculate :
8.1. The velocity after 12 seconds.
8.2. The displacement when the velocity is 18ms?​

#8.1

#8.2

Use third equation of kinematics

Question 8.1

• from first newtons equation of motion:

• u → 0

• a → 5.5 m/s²

• t → 12 s

Question 8.2

• from third newton equation of motion:

• s → displacement

• u → 0

• a → 5.5 m/s²

• v → 18 m/s

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
