Answer:
The speed of projection is 34 m/s.
Explanation:
Height of building, h = 51 m
horizontal distance, d = 74 m
time, t = 8 s
Let the angle is A and the speed is u.
d = u cos A x t
74 = u cos A x 8
u cos A = 9.25 .... (1)
Use second equation of motion
Squaring and adding both the equations
Newton's law applies here because an object in motion (your body) stays the speed that you were going, so if you were hit, your body would keep going when the car is stopped. This causes your body (especially your neck) to whip back and possible break.
Answer:
The process is a mechanism known as mantle convection
Explanation:
Mantle convection is the driving mechanism for plate tectonics, which is the process ultimately responsible for producing earthquakes, mountain ranges, and volcanos on Earth.
This mechanism occurs in four different patterns
- Collision: this is the shoving together of two continental plates
- Subduction: this is the plunging of one plate beneath another
- Spreading: this is the pushing apart of two plates
- Transform faulting: this occurs when two plates slide past each other
