. On a horizontal, frictionless surface, a 9.00 kg object initially moving east at 4.00 m/s collides with a 3.00 kg object that was initially moving north at 10.0 m/s. After the collision, the three-kilogram object moves with a velocity o 12.00 m/s directed 32.0o north of east. (a) Calculate the velocity of the nine-kilogram object after the collision, and (b) determine by calculation the type of collision that occurred.

A 2.20-kg object is attached to a spring and placed on frictionless, horizontal surface. A horizontal force of 18.0 N is required to hold the object at rest when it is pulled 0.200 m from its equilibrium position (the origin of the x axis). The object is now released from rest from this stretched position, and it subsequently undergoes simple harmonic oscillations. (a) Find the force constant of the spring.

a)An object of mass ?m rests on a horizontal frictionless surface. A constant horizontal force of magnitude ?F is applied to the object. This force produces an acceleration: always only if ?F is larger than the weight of the object only while the object suddenly changes from rest to motion only if ?F is increasing choice A b)Now let there be friction between the surface and the object. If the object has a mass of 10 kg, and ??μs =...
