Consider a football halfback with a mass of 90 kg running down the football field and encountering a collision with a defensive back. If the halfback experiences a force of 800 N for 0.9 seconds, how much impulse will he experience?

Impulse:

Explanation:

The impulse experienced by an object is given by:

Where

F is the magnitude of the force exerted on the object

is the time interval during which the force is applied

I is the impulse

For the halfback in this problem, we have:

F = 800 N is the force experienced

is the time interval

Therefore, the impulse experienced is

And this impulse is also equal to the change in momentum of the halfback.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

pls mark as brainliest

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
