Ahockey player makes a slap shot exerting a constant force of 40.0 newtons on the puck for .2 seconds. what is the magnitude of the impulse given to the puck?

Magnitude of impulsive force is 8 N.s.

Explanation:

Given:

Force acting on the puck is,

Time interval for which the force acts is,

We are asked to find the impulsive force.

Impulsive force acting on a body is the sudden change in the momentum of the body due to the application of a large constant force for a very small interval of time.

Here, the hockey player applies a large force of 40 N for a very short interval of time. So, the impact on the puck is measured as Impulse and is represented by 'J'.

Impulse in terms of applied force and time interval is given as:

Plug in the given values and solve for 'J'. This gives,

Therefore, the magnitude of impulsive force is 8 N.s.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
