Question
Lycamobile 9:16 AM angle of 53° with the borizental. How much work does the person does? 588 b. 289 3853 d. 4903 98J 19. A block attached to a cord of length L -1m, is released from the position shown when the angle ? is 37°. If the mass of the block is 0.1 kg find the magnitude of the linear momentum of the block when is passing at the lowest point. a. 1.97 kg m's b. 0.197 kg m/s .0.3kg m's d. 3.92 kg m/'s e. None of the above 20. A particle of mass 0.2 kg is moving in one dimension with a position given by s(t . Calculate the mementum p of the particle when the time is 2s (4r2+6r) a. 11 kgm/s b. 1.6 kgm/s c.0.4 kgm/s d. 2.2 kgm/s e. 1.9 kgms 21. At the instant the vector position of a particle of mass 0.1 kg is -(4m and the vector velocity is-81 ms. Calculate the vector angular momentum L . ?. 32£ kgrap? af the ahave eylinder rotates with respect to a fix axis that pass through the center of mass of the ey linder. Find its angular acceleration. Assame the momeat of inertia of the cyliader MR 2 22. A selid ey linder of mass 80 kg and radius 0.5 m expericnces a force of 60 N. Thes 6eNExplanation / Answer
here,
18)
mass , m = 10 kg
force applied , F = 80 N
s = 6 m , theta = 53 degree
the work done , W = F * s * cos(theta)
W = 80 * 6 * cos(53) J
W = 289 J
the work done is b) 289 J
