Answer :
block 1 of mass 56 kg is at position <9, 7, 0> m.
block 2 of mass 1450 kg is located at position <14, 7, 0> m.
1) gravitational force acting on block 2 due to block 1
F = G*m1*m2/r^2
Fx = G*m1*m2/(x1 - x2)^2
Fy = 0 (same height)
Fz = 0 (same plane)
Fx = G*(56*1450) / (9-14)^2
put G = 6.674 08 x 10-11 m3 kg-1 s-2
we get = Fx = 21.68 x 10-8 N
Plug and chug. The Force acts towards the the Block 1 so the vector
will be
F = (-Fx,0,0)
F = <-21.68 x 10-8 , 0 , 0 > N
2) For the 2nd part you need the acceleration, g, of the
block.
g = G*m2/r^2
momentum = m*v = m*g*t
momentum = < -1.3903e-8, 0, 0 > kg·m/s
3) for block 2
momentum = < -1.3903e-8, 0, 0 > kg·m/s
4) Block 1 is moving faster than block 2.

Problem 2.14 Your answer is partially correct. Try again A 0.52 kg block of ice is sliding by you on a very slippery floor at 2.4 m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with the ice block for 0.0022 seconds. The bick eventually slides at an angleof 29 degrees from its original direction labeled θ in the d agram). The overhead view shown in the diagram is a...
Chapter 07, Problem 36 GO Your answer is partially correct. Try again. Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision Momentum is conserved. Object A has a mass of mA = 16.6 kg and an initial velocity of VOA 7.80 m/s, due east. Object B, however, has a mass of mB = 28.2 kg and an initial velocity of V08-5.83 m/s, due north. Find the...
Your answer is partially correct. Try again. A 6.98-9 bullet is moving horizontally with a velocity of +364 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks...

Your answer is partially correct. Try again. Two identical 0.12 kg blocks (labeled 1 and 2) are initially at rest on a nearly frictionless surface, connected by an unstretched spring, as shown in the upper diagram, where x2 = 0.05 m. Then a constant force of 7 N to the right is applied to block 2, and at a later time the blocks are in the new positions shown in the lower diagram, where xi = 0.02 m and x3...
