An object of mass m1=10 kg traveeling at a speed of 24 m/s due east collides with an object of mass m2=20kg initally at rest. After the collision m1 travels due north with a speed of 10 m/s. the objects do not stick together

A) What are the magnitude and direction of the velocity of m2 just after the collision
B) Was this a totally elastic collision? explain

using conservation of momentum i got 70 m/s, butit dosent seem so simple. and i have no idea of the collision is totally elastic.
