Homework Statement The problem is in the attached image Homework Equations The Attempt at a Solution I understand that the diagram of A is displaying negative acceleration and the diagram of B is displaying positive acceleration. However, I am struggling to find an answer for the...

as much as i hate to ask for a straight answer (with a minor explanation) from you guys, i think it would be beneficial because i simply can't get it and I've inputted about 12 answers into this program

still can't get it. i tried calculating the area underneath both of those and got 10 m/s, but that wasn't the velocity of the acceleration graph... I am not sure what to do

how would i isolate

by integrating the area at that point to the x axis? 1/2(2)(-20) ?

Homework Statement Find each particle's velocity at t=7.0s. Work with the geometry of the graphs, not with kinematic equations.Homework Equations The Attempt at a Solution I'm not sure how to arrive at an answer. For the previous question (velocity from graph b) I found the value of -20 m/s by...

i forgot to add that this is part of a collision simulator

Homework Statement the info/problem are in the attached images Homework Equations The Attempt at a Solution i'm not sure what to state.

i think i got it -360 n*s = 60(vf-7) -6=vf-7 vf=1 m/s ?

impulse. however, i don't know if i did part A right and i don't know if they want me to use all the information in question B... and i do not understand what they mean by AFTER 1.20 seconds

i believe I've found the integral in part A but i don't know what part b means by "find the velocity at 1.20 seconds" i've got the following information compiled for part b) fnet(delta t) = m (delta v) delta t = 1.20 seconds Fnet = ? m = 60 kg vi = 7.0 m/s vf = ? my problem is that i don't...

not sure

Homework Statement Use the concepts of momentum and Newton’s second law to explain why a motorcycle can accelerate at a greater rate than a large truck. Homework Equations The Attempt at a Solution The motorcycle will accelerate at a greater rate because the truck has a...

Homework Statement Homework Equations fnet(delta t) = m (delta v) The Attempt at a Solution I need some help on question b ASAP (i'm not sure what the question means when it says find the velocity AT THE END of the 1.20 sec impact) and i would like for someone to check if I've...
