i got it now its sqrt(of horizontal direction ^2 + vertical direction ^2)

I now think block 2 would exert a force to block 3 equal to the combined weight of the 2 books above it which is f=2(mg) = 2*10*9.8 = 196 N but i still get it wrong

Homework Statement Scientists want to place a 2900.0 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 1.6 times the radius of Mars above the surface of the planet. Here is some information that will help solve this problem: mmars = 6.4191 x...

What do you think ? I am worried about the radius because of the 1.6 times m= 6.4191 x 10^23 G = is either 9.8 or 6.67428 x 10^-11 M= 2900 r=(1.6* 3.397 x 10^6) or 3.397 x 10^6

Four blocks EACH of mass m = 10.0 kg are arranged as shown in the picture, on top of a frictionless table. A hand touching block 1 applies a force of Fh1 = 90.0 N to the right. The coefficient of friction between the blocks is sufficient to keep the blocks from moving with respect to each other...

this is the pic

springs are connected is m1 at top is connected to m2 in middle which is connected to m3 in the bottom

Hi I am not sure my answer is supposed to be in cm but I am sure I have done it right puzzling indeed

What is the distance the upper spring is extended from its unstretched length? Now, three masses m1 = 3.3 kg, m2 = 9.9 kg and m3 = 6.6 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant of 229.57N/m Now the elevator is moving downward...

Can you tell me if my answers and sign are correct ? A car is traveling around a horizontal circular track with radius r = 250.0 m at a constant speed v = 18.0 m/s as shown. The angle θA = 19.0° above the x axis, and the angle θB = 60.0° below the x axis. What is the x component of the car’s...

in the same problem i had a question What is the horizontal force on block A due to block B? i got -15.4 and I got it right so how come that one can be -15.4 and this one is just 7.7

wouldnt it be -7.7 because of negative direction so is the horizontal force on block B 7.7 ?

Three blocks, each of mass 7.0 kg are on a frictionless table. A hand pushes on the left most box (A) such that the three boxes accelerate in the positive horizontal direction as shown at a rate of a = 1.1 m/s2. What is the net horizontal force on block B? =15.4 N What is the horizontal...

You are on a train traveling east at speed of 14.0 m/s with respect to the ground. if you walk west toward the back of the train, with a speed of 1.4 m/s with respect to the train, what is your velocity with respect to the ground? I got the answer as 12.6 m/s east but is my answer going to...
