1 A Particle With A Mass Of 4 Kg Has Position Vector In Meter Given By R 31 I 2tj 3tk Where T Is The Time In Seco 2 (28.14 KiB) Viewed 24 times
1. A particle with a mass of 4 kg has position vector in meter given by r = 31-i - 2tj- 3tk, where t is the time in seconds. For t = 3 s determine the magnitude of the angular momentum of the particle and the magnitude of the moment of all forces on the partie, both about the origin of coordinates. H=389 N.m.s; M = 260 N.M
1442 km/h Figure 2 -Z VBIA = 26.0 m/s aA/B = 1.98 m/s2 33.7° South of west Figure 3 250 m 3. At the instant shown car A is traveling with a velocity of 30 m/s and has an acceleration of 2 m/s' along the highway (Figure 3). At the instant B is traveling on the trumpent interchange curve with a speed of 15 m/s, which is decreasing at 0.8 m/s Determine the relative velocity and relative acceleration of B with respect A at this instant. Ans. V/A =26 m/s, anB = 1.98 m/s?
