3 Procedurea. Determine the mass of the wooden block.b. Clean the surfaces of the black and laminated sheet.c. If the laminated sheet is not already fastened to the bench surface, fasten it using the providedthumb tacks or cello-tape.d. Place the wooden surface of the block on the laminated sheet.e. Ensuring that the spring balance is parallel to the surface of the laminated sheet, pull at thewooden block gently until it just moves and record the force just before the block moves.Record the value of this force as𝑓𝑠.f. Repeat step (e) for two other readings and find the average value,(𝑓𝑠)𝑎𝑣.g. Now pull the wooden block so that it moves uniformly motion and record the force on thespring balance as 𝑓𝑘.h. Repeat step (g) for two other readings and find the average value, (𝑓𝑘)𝑎𝑣.i. Place a 100 g mass on the wooden block and repeat the measurements above, and then increasethe mass from 100 g to 500 g to generate at least five data points.j. Record the data as in Tables 1 and 2.k. Now place the rubber surface of the block in the laminated sheet. Repeat the steps (e) to (i)and record your data as in Tables 3 and 4.Wooden surface on laminated sheetTable 1Mass (g)±Normal Reaction(N) ±(𝑓𝑠)1(N) ± (𝑓𝑠)2(N) ± (𝑓𝑠)3(N) ± (𝑓𝑠)𝑎𝑣(N)±

Which tools would be needed to measure the size and the mass of a block of wood?

A 7.6-kg block is held in place against the spring by a 68-N horizontal external force. The external force is removed, and the block is projected with a velocity v1 = 3 m/s upon separation from the spring. The block descends a ramp and has a velocity v2 = 3.5 m/s at the bottom.The track is frictionless between points A and B. The block enters a rough section at B, extending to E.  The coefficient of kinetic friction is 0.39. The velocity of the block is v3 = 1.8 m/s at C. The block moves on to D, where it stops.What was the initial compression of the spring?Express your answer in cm, to at least one digit after the decimal point.

A light spring with force constant 3.85 N/m is compressed by 8.00 cm as it is heldbetween a 0.250 kg block on the left and a 0.500 kg block on the right, both resting ona horizontal surface. The spring exerts a force on each block, tending to push the blocksapart. The blocks are simultaneously released from rest. Find the acceleration withwhich each block starts to move, given that the coefficient of kinetic friction betweeneach block and the surface is:(a) 0(b) 0.100(c) 0.462

Two wooden blocks of masses 5 kg and 3 kg are connected by a massless rope. The 5 kg block is pulled by a horizontal force of 40 N.[All floors are frictionless. Ignore the vertical forces.](i) Find the acceleration of the blocks.(ii) Find the tension in the string

Block A𝐴 in (Figure 1) has mass 1.00 kgkg, and block B𝐵 has mass 3.00 kgkg. The blocks are forced together, compressing a spring S𝑆 between them; then the system is released from rest on a level, frictionless surface. The spring, which has negligible mass, is not fastened to either block and drops to the surface after it has expanded. Block B𝐵 acquires a speed of 1.30 m/sm/s.Figure1 of 1Part AWhat is the final speed of block A𝐴?Express your answer in meters per second.Activate to select the appropriates template from the following choices.
