yes we'r ignoring air resistance and hmm it makes a lot more sense now LOL man my brain works slow.. =| thnx a lot :-)

My physics teacher last year did not teach us anything about projectiles i had to learn everything by reading from textbooks. I tried finding the answers to these questions but couldn't think of anything so if some1 could please help me and explain the why behind the answer. A.) For a...

Homework Statement A 2.50X102Kg weight is suspended from two ropes that are angled at 30.0degrees and 60.0 degrees above horizontal. What is the tension in the two ropes? The work i did is in the attachements .. The answer sheet says the answer of the two forces is 1420 N and 2470 N i...

ohhh Thnxxx :D

man yur great =P i have a really tough question i was not able to figure out want to help me with that :$

yeaaa kinda ..soo the total weight subtracted from Tension gives me the net force then i apply the forumlaa .. OH that makes so much senseee =) THNXXX :D

so the formula would be changed to F= (mg)a ?

Homework Statement A 2.00X101 kg mass is pulled upwards with constant acceleration by a cable attached to a motor. The cable can withstand a maximum tension of 5.00X102 N. What is the maximum acceleration possible? The answer sheet says the answer is 15.2m/s2 Homework Equations F=ma...

yea that makes a lot of sense thanxx a lot :D

Homework Statement A 5.0 kg mass is held against a wall with which it has a coefficient of static friction of 0.85. What is the minimum horizontal force required to hold the mass against the wall ? The teacher said answer is 58 N .. i can't get to that answer.. Homework Equations...

or do i use half of g (9.81/2) as the given acceleration ?

i get that but the problem i face is .. there is no given acceleration =(

Homework Statement On a cold day, a 35kg child takes a 3.5 kg toboggan to a snowy hill to slide down it. There is Us = 0.15 and Uk=0.05 between the hill and the toboggan. What is the minimum incline required before the toboggan will slide? What angle is required for the child to accelerate...
