hi

does the question have any additional information?

for 36. the impulse momentum should be equal to the area under the curve

impulse momentum = F * change t = area under the curve

= 4 * 1 + 2 * 2 + (2 * 2)/2 = 10N

not sure how to calculate **average** impulse

for 37. momentum = impulse momentum

so we should find the same result as for 36.

hello!

unfortunately, there is not extra information but the answer key states 45

hi

i asked chatgpt, to find the **average** impulse momentum you need to the the integral of the area under the curve, and integrals aren’t on the imat syllabus so we won’t have a question like this on the exam

oh right! thanks for the explanation

and also i believe integral is already means the area itself but i don’t think this would get asked in the exam
