Two cars collide at an intersection. car a, with a mass of 2000 kg, is going from west to east, while car b, of mass 1500 kg, is going from north to south at 17.0 m/s. as a result of this collision, the two cars become enmeshed and move as one afterwards. in your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 60.0 degrees south of east from the point of impact. how fast were the enmeshed cars moving just after the collision?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
