    Forces Exerted by 1kg, 2kg, and 3kg Blocks

    Ahhh yes! Applied force - F2 = 1 kg (2m/s^2) 12N-10N=2N I believe that I finally understand what you were trying to explain. Thank you so much for your help and patience... It's been a long weekend.

    Forces Exerted by 1kg, 2kg, and 3kg Blocks

    Errr... This is painful... Thank you to the repliers, especially saket. You told me that I did arrive to the correct force between 2-3, 6 N. Seeing as the net force equals 12 like you said, would that have to lead me to believe that 12-6 equals Fnet-F2= F1= 6? Thank you for being so patient.

    Forces Exerted by 1kg, 2kg, and 3kg Blocks

    Would the force exerted between 2-3 = f=ma x=3(2) x=6 N Force between 1-2 x= 2(2) x= 4 N Seems incredibly simple so I'm sure there must be some sort of problem somewhere along the way.

    Forces Exerted by 1kg, 2kg, and 3kg Blocks

    Well finding the acceleration of the system was easy enough/ f=ma 12=6(x) x=2 I drew the fbd however I'm having trouble differentiating between the different blocks. For instance, Block 1- 1 kg acting on block 2- 2 kg... When I use the formula f=ma clearly I will arrive at two different...

    Forces Exerted by 1kg, 2kg, and 3kg Blocks

    Homework Statement Blocks with masses of 1 kg, 2 kg, and 3 kg are lined up in a row on a frictionless table. All three are pushed forward by a 12 N force applied to the 1 kg block. How much force does the 2 kg block exert on the 3 kg block? How much force does the 2 kg block exert on the...

    Acceleration Due to Gravity of the Sun

    I'm using the distance from the Earth to the Sun. 1.50 x 10^11 = r r^2 = 2.25*10^22

    Acceleration Due to Gravity of the Sun

    How about this... ((6.67*10^(-11)) * (1.99*10^30))/ (2.25*10^22) = 0.005899244 m/s^2 ~0.00

    How Far Does a Skateboarder Land from a Ramp?

    Hmm... That wasn't even close... Let me try this again. cos30(7)=vx= 6.06 m/s sin30(7)=vy= 3.5 m/s -1=3.5(t)+.5(-9.8)(t^2) 0=-4.9t^2+3.5t+1 t= 0.933 s x= (6.06)(.933)+.5(0)(.933)^2 x= 5.65 m How does that look?

    What is the sailboat's speed and direction after being hit by a gust of wind?

    Thank you very much for your help... I think this is correct... could you please review it for me? cos40(.8)= ax= 0.613 m/s^2 sin40(.8)= ay= 0.514 m/s^2 Vfx= 5+(0.613)(6)= 8.68 m/s Vfy= 5+(0.514)(6)= 8.08 m/s V= sqrt(8.68^2+8.08^2)= 11.86 m/s xf=0+5(6)+.5(.613)(6)^2= 41.034 m...

    What is the sailboat's speed and direction after being hit by a gust of wind?

    Homework Statement A sailboat is traveling east at 5.0 m/s. A sudden gust of wind gives the boat an acceleration of 0.80 m/s^2 at 40 degrees north of east. What are the boat's speed and direction 6.0 s later when the gust subsides? Homework Equations xf=xi+vix(delta t)+1/2ax(delta t)^2...

    Will the Farmer Move the Stubborn Mule?

    Homework Statement A stubborn 120 kg mule sits down and refuses to move. To drag the mule to the barn, the exasperated farmer ties a rope around the mule and pulls with his maximum force of 800 N. The coefficients of friction between the mule and the ground are mu,s = 0.8 and mu,k = 0.5. Is...
