Impulse = change in momentum
Impulse = 2.3 (12 - 17)
Impulse = -11.5
Magnitude of Impulse = 11.5 Kg.m/s
theta = arctan (17 / 12)
theta = 54.78 degree North of east.
theta = 90 - 54.78 = 35.2 degree east of north
Therefore, correct option is A

Chapter 07, Problem 36 GO Object A is moving due east, while object is moving due north. They collide and stick together in a completely inelastic collision. Momentum is conserved. Object A has a mass of ms -16.2 kg and an initial velocity of Tox - 7.34 m/s, due cast. Object B, however, has a mass of m -28.3 kg and an initial velocity of Pop - 5.40 m/s, due north. Find the (a) magnitude and (b) direction of the...
1) . A passenger on a moving train walks at a speed of 1.90 m/s due north relative to the train. The passenger's speed with respect to the ground is 4.5 m/s at an angle of 31.0° west of north. What are the magnitude and direction of the velocity of the train relative to the ground? 2) A ship sets sail from Rotterdam, The Netherlands, heading due north at 8.00 m/s relative to the water. The local ocean current is...

Linear Momentum of an object is conserved At all times b. Only when the net external force on the object is Zero When the net external torque on the object is Zero d. Never A truck of mass 4000 (kg) is moving at 10 (m/s). A car of mass 1000 (kg) is moving at 40 (m/s). So, the truck’s momentum, compared to the car, is Greater b. Smaller c. the same d. Cannot say without knowing their accelerations A 1000...
