Question

oahttp://wwwwebassign nment -Responses/last?dep 16692928 sset 4 P020 Two packing crates of masses m 10.0 kg and m2 4.00 kg are connected by a light string that passes over a frictionless pulley as in Figure P4.26 The 4.00 kg crater lies on a smooth incline of angle 41.00 Find the acceleration of the 4.00 kg crate. m/s2 (up the incline) Find the tension in the string Figure P4.26 -3 points SerEssent 4 P021 My Notes Ask Your Assume that the three blocks portrayed in Figure P427 move on a frictionless surface and that a F 50 N force acts as shown on the m 4.0 kg block o e-e @9.a .E

Explanation / Answer

on m1:

10g - T = 10a ..... (i)

on m2:

T - 4 g sin41 = 4 a .... (ii)

(i) + (ii) =>

10g - 4 g sin41 = 14 a

a = 5.17 m/s^2 ......Ans

(b) T = 10 (9.81 - 5.17) = 46.4 N
