Select all of the following that equal an impulse of 10 units a).force = 20, time = 1/2
b). force = 3, time = 4
c). force = 5, time = 2
d). force = 10, time = 1

A, C and D

Explanation:

The impulse is defined as the product between the force (F) and the time of the collision (t):

Let's apply the formula to calculate the impulse for each situation:

A)

B)

C)

D)

We see that the situations in which the impulse is equal to 10 units are:

A, C and D

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
