mechanics help again! Watch
I found, invsin 0.6 = 37...
sin 37 * 60 * 9.81,
then put that into a kinematic equation, the one with 2as involved ( i dont have the squared signs so wont write it out) and i got 59ms as answer... when asnwer is 7.67, please help
And you are finding
Using You do get
EDIT: You haven't forgoten to square rootm it have you as it is
i thought it meant, invsin3/5 = the angle size, so i did that, found out Sin angle, and then did what you had done
Why is the acceleration just, g * 3/5, is it not, the inv sin of 3/5 ?
why do we not include the 60kg?
usually, when finding down the slope
Sin theta * mass * grav... why do we miss out mass?
Therefore, Force downslope = 3/5 mg
Using F=ma, ma=3/5mg
Acceleration down the slope is independant of mass, and [usually] you only need to consider it when you are dealing with friction or another non-gravity-related force.
Thank you so much That really helped, the only thing i dont understnad is what
also thank you colin :P yes those crazy people!
Ohhhhhhh so the mass cancels out, now i see it, thank you both
Now im trying a question which is the opposite, up a slope, haha, who knows how many days till i complete this one hah! :P
