A 4.00 kg ball is moving at 4.00 m/s to the EAST and a 6.00 kg ball is moving at 3.00 m/s to the NORTH. The total momentum of the system is:.A. 14.2 kg m/s at an angle of 48.4 degrees SOUTH of EAST. B. 48.2 kg m/s at an angle of 24.2 degrees SOUTH of EAST. C. 48.2 kg m/s at an angle of 48.4 degrees NORTH of EAST. D. 24.1 kg m/s at an angle of 24.2 degrees SOUTH of EAST. E. 24.1 kg m/s at an angles of 48.4 degrees NORTH of EAST.

Aforce of 34n stretches a very light ideal spring 0.73 m from equilibrium, what is the force constant (spring constant) of the spring? (a) 47n/m (b) 38n/m (c) 53n/m (d) 25n/m

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
