(II) As shown in Fig. 4-41, five balls (masses 2.00, 2.05, 2.10, 2.15, 2.20kg) hang from a crossbar. Each mass is supported by “5-lb test” fishing line which will break when its tension force exceeds 22.2 N (= 5 lb). When this device is placed in an elevator, which accelerates upward, to the 2.05 and 2.00 kg masses do not break. Within what range is the elevator’s acceleration?

- I think that friction on the x axis is zero so would I add all the weight up on the y axis and divide by the gravity?arrow_forward13–35. The coefficient of static friction between the 200-kg crate and the flat bed of the truck is µ, = 0.3. Determine the shortest time for the truck to reach a speed of 60 km/h, starting from rest with constant acceleration, so that the crate does not slip.arrow_forward(II) Arlene is to walk across a “high wire" strung horizontally between two buildings 10.0 m apart. The sag in the rope when she is at the midpoint is 10.0°, as shown in Fig. 4-47. If her mass is 50.0 kg, what is the tension in the rope at this point? 10.0° FIGURE 4-47 Problem 23.arrow_forward

A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end (Fig. 4–45). Determine the force that the table exerts on the box if the weight hanging on the other side of the pulley weighs (a) 30.0 N, (b) 60.0 N, and (c) 90.0 N.
