T=163 N (k) Suppose m1-5 kg and m2-9 kg. What is the value of the acceleration?...
Question 9 16 pts Two crates, m1 = 20 kg and m2 - 8 kg are in contact with each other on a horizontal, frictionless surface as shown in the figure. A pushing force, P, of 80 N acts on my, at an angle of 20° below the horizontal, but both crates accelerate together, along the ground. a) Draw a free body diagram for each crate. Clearly indicate which forces, if any, are Newton's 3rd law pair forces. b) Find...
need the “exercise” answered. thanks
PRACTICE IT Use the worked example above to help you solve this problem. A block with mass m 4.30 kg and a ball with mass m2 = 7.50 kg are connected by a light string that passes over a frictionless pulley, as shown in figure (a). The coefficient of kinetic friction between the block and the surface is 0.300. (a) Find the acceleration of the two objects and the tension in the string. a= 5.16...
please help
2. Block A has a mass of 40 kg, and block B has a mass of8 kg. The coefficients of friction between all surfaces of contact are 0.2 and 4k 0.15. Determine (a) the accelerations of blocks A and B, (b) the tension in the cord, and (c) the velocities of blocks A and B after the block A has moved bv 0.5 m. Assume that initially the velocity of block A is 0 15° proach: . Isolate...

Procedure: Materials: 1. apparatus 2. 2 pieces of metal track 3. plastic or metal ball 4. timer 5. meter stick 6. micrometer 7. 2 photogates Assemble your ramp as shown in Figure (1) in the next page. Then set up photogates in location 2 and 3. Measure the diameter (in m) of the metal balls (you will need it for speed calculations). Then, measure the weight (mass) of the ball (in kg). To have a better measurement of the time,...
