Answer:
a) 378Ns
b) 477.27N
Explanation:
Impulse is the defined as the product of the applied force and time taken. This is expressed according to the formula
I = Ft = m(v-u)
m is the mass = 70kg
v is the final velocity = 5.4m/s
u is the initial velocity = 0m/s
Get the impulse
I = m(v-u)
I = 70(5.4-0)
I = 70(5.4)
I = 378Ns
b) Average total force is expressed as
F = ma (Newton's second law)
F = m(v-u)/t
F = 378/0.792
F = 477.27N
Hence the average total force experienced by a 70.0-kg passenger in the car during the time the car accelerates is 477.27N

The acceleration of one of those bugs is equal to 305mi/s.
<h3>Acceleration calculation</h3>
To calculate the insect's acceleration, the action and reaction force of the impact must be considered.
As the insect will hit the helmet, the force it hits is the same force it receives, so we can make the following expression:
<em>Speed has been converted to miles per second</em>
So, the acceleration of one of those bugs is equal to 305mi/s.

Answer:
Scientific theory is a well-supported explanation of an occurrence of a natural phenomenon. Scientific law is a description of a natural phenomenon that is always observed to occur under specific circumstances.
