(b) With µ =0.2, what should be the new weight of block B so that both blocks A and B will move with constant velocity? 3. Determine the tension in each cord if the weight of the suspended object is 200N, refer to figure 3. 4. You’re part of a mission carrying humans to the surface of the planet Mars, which has radius of 3.4 x 10 6 m and a mass 6.42 x 10 23 kg. The earth weight of the mars lander is 39,200 N. Calculate it weight F g and the gravitation g due to the gravity of Mars. (a) 6 x 10 6 m above the surface of Mars and (b) at the surface of Mars. Figure 3 Figure 2 Figure 1...
