Answer:
When a car stops suddenly, the inertia the keeps you moving forward will finally stop and give you whiplash, which could seriously injure or even kill a baby. With the seat turned back, the force will be decreased dramatically, and prevent any fatal harm.
Answer:
Acceleration of the platform = - 1.8 m/s²
Explanation:
The net force acting on a body accelerates the body in the same direction as that in which the resultant is applied.
Writing the force balance for the setup,
ma = 800 - mg
100a = 800 - 100×9.8
100a = - 180
100a = - 180
a = - 1.8 m/s²
This means the body falls downwards.
A 'vector' is a measurement that has a magnitude and a direction.
For the vector given here, "<em>15 ft/s</em>" is the magnitude, and "down" is the direction.
