The human body can survive a negative acceleration trauma incident (sudden stop) if the magnitude of the acceleration is less th

an 250 m/s2 (approximately 25g). if you are in an automobile accident with an initial speed of 76 km/h (47 mi/h) and are stopped by an airbag that inflates from the dashboard, over what distance must the airbag stop you if you are to survive the crash?

Let d = the required stopping distance of the air bag.
The initial velocity is
u = 76 km/h
   = (76000/3600 m/s)
  = 21.111 m/s

The maximum acceleration (actually deceleration) is -250 m/s².
The final velocity is zero, therefore
0² = (21.111 m/s)² + 2*(-250 m/s²)*(d m)
Obtain
d = 0.8914 m

Because the acceleration decreases when the stopping distance increases, a stopping distance of 1 m would be a good design choice.

Answer:
The stopping distance is 0.9 m (nearest tenth)

A motorcyclist travels with an average speed of 6 m/s . If the cyclist is going to a friend's house 36 m away , how much time wi
vodka [1.7K]

Answer:

<h2>6 s</h2>

Explanation:

The time taken by the cyclist can be found by using the formula

t  = \frac{d}{v}  \\

v is the velocity

d is the distance

From the question we have

t =  \frac{36}{6}  \\  = 6

We have the final answer as

<h3>6 s</h3>

A student throws a ball upward with a velocity of 35 m/s. What is the acceleration of the ball as it rises to the top of its arc
lora16 [44]

Answer:

The acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.

Explanation:

Let suppose that maximum height of the arc is so small in comparison with the radius of the Earth.

Since the ball is launched upwards, then the ball experiments a free-fall motion, that is, an uniform accelerated motion in which the element is accelerated by gravity. Then, the acceleration experimented by the motion remains constant at every instant and position.

Besides, the gravitational acceleration in the Earth and, in consequence, the acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.
