Answer 1

mass of particle, m= 1.1kg. velocity v = (7.11 + 5.5 7 ) m/s particles position = (3 9 + 4.3 F Im so, angular momentum with respect to the origin, I= 8x mv = m (8x²) = 11( 39 + 4.3 %) x (7.11 + 5.5 7 )] as kg. m/s =(-26.0151 +33.583 9 - 23.43 û ) Kg. m7 a 9 û ~ (-26 î + 34 9 - 23 R ) Kg. my 03 4.3 Part B (in two significant figures) 17.1 5.5 o Torque, - 165.5x4.3) + (4.3x71)+K(387) = -23.651 + 30.5 31 – 21.3 E = 1 (39 + 4.3 ? ) x 4.37] N.m = f 12.9 R + 18.99 9 ) N.m ~ (-13 û + 18 7 ) N.m (in two significant figures) ?= 8x7
