WebQuestion: QUESTION 11 velocity (m/s) 20 10 time (s) 0 20 40 60 8.0 -10 -20 FIGURE 2-2 in Fig. 2-2, what is the acceleration at 1.0 s? O-2.5 m/s2 O 20 m/s2 O 10 m/s2 00 This … WebThat's why 8 m/s also became the height of the triangle, since the bottom of the triangle on the graph was at vi = 5 m/s, and the top of the triangle was at vf = 13 m/s. The graph (velocity vs time) is a straight line that rises with a constant slope of 2, because the velocity is increasing at a steady rate of 2 m/s (graph goes up 2) per second ...

WebThe vacuum cleaner's armature shaft S shown in (Figure 1) rotates with an angular acceleration of α=4ω3/4rad/s2, where ω is in Determine the brush's angular velocity when t=5 s, starting from ω0=0.50rad/s, at t=0. The radii of the shaft and the brush are 0.35 in. and 1.0 in., respectively. rad/s Neglect the thickness of the drive belt. WebIn an engine, a piston oscillates with simple harmonic motion so that its position varies according to the expression x=5.00cos (2t+6) where x is in centimeters and t is in seconds. At t = 0, find (a) the position of the piston, (b) its velocity, and (c) its acceleration. Find (d) the period and (e) the amplitude of the motion. arrow_forward new heart dramacool

WebAug 18, 2012 · Homework Statement. A proton (+e) accelerates from rest in a uniform electric field of 640 N/C. At some later time, the proton's speed is 1.20 x 10^6 m/s. Find the acceleration of the proton. The mass of a proton is 1.67x10^-27 … Web= 16:817rad=s2 3) At this moment, the acceleration of the center of mass is a = (L=4) . So the second Newton law gives mg T′ L = Fnet = ma = m(L=4) Solving for the tension T′ L = 4 7 mg T′ L = 0:813N 4) Using conservation of energy 1 2 I!2 = mg L 4 Solving for the angular speed7! = √ mgL 2I = √ 6g 7L! = 5:800rad=s 5) Acceleration of ...
