Using an equation can be very confusing, ppl tend to try to put in the information in the question, into the equation even if tht is not applicable, so my advise wud be to disregard the equation, and try understanding the scenario given in the question. If u have ur basic right, u shud get to...- qffdhruba

Mechanics M1: Post your doubt here
U can find acceleration by: a = -0.12/0.15 = -0.8 (through F=ma) So there is a negative acceleration, due to the resistive frictional force of 0.12N at 2s the velocity is: v = 3 + 2(-0.8) = 1.4 (through v=u + at) KE after collision: (0.5(0.15)(1.4)^2) - 0.072 = 0.075 Velocity after... -

M1 ON 13 MAY ,WHO HAS THE BEST PREPATION,Post your doubts here?
I think ur graph is wrong, because after collision the motion is towards a direction opposite to the initial motion. therefore, the velocity becomes negative, i think the graph shud be this: -
A level Biology: Post your doubts here!
The confusion may arise between C and D.... The stroke volume depends on the contraction of the cardiac muscles.... So the muscles cannot exert a infinite amount of pressure.... Cause their strength of contraction is limited by the ATP formed in the muscle tissues.... Therefore the volume pumped... -
