Question

Two objects have an elastic collision with each other. Use this information to help you fill in the missing data in the table below Before After collision 20 50 collisiorn KA 12 otal Momentum Data Table Based on the momentum data in the table below, identify what kind of motion each object is exhibiting. Elapsed Time P2x (N-s) 81 80 72 62 48 p3x (N-s) 84 103 108 116 120 P4x (N-s) -14 -14 -14 -14 -14 Pix (N-s) 0 3 0 .Select- Submit Answer 7. -110 points Impulse There are two ice skaters, Pat & Chris. Pat pushes Chris north with 121 N of force for 14 s. Determine how much impulse (magnitude & direction) Pat delivers to Chris and how much impulse Chris delivers to Pat. Express your answers using appropriate mks units. Impulse Pat imparts to Chris- Choose direction -Choose direction Impulse Chris imparts to Pat 8.-/10 points Momentum: Completely inelastic A 4.00 g bullet is fired horizontally at a speed of 242 m/s into a 1.50 kg wooden block resting on a frictionless horizontal surface. Determine how fast the block will be moving if the bullet becomes imbedded in the block. Express your answer using appropriate mks units

Explanation / Answer

Total K = 50 +20 = 70 J

Total Kinetic energy will remain same before and after the collision (70 J)

KA + 12 = 70

KA = 58 J

1 is at rest

2 is having retardation

3 is having acceleration

4 is having uniform velocity along negative x- axis

7) F = 121 N

t = 14 s

Impulse = Ft

Impulse = 121 X 14 = 1694 Ns

Impulse Pat imparts to chris = 1694 Ns towards north

Impulse Chris imparts to Pat =1694NS towards south

8)Momentum before collision = momentum after collision

mu = (m +M)v

0.004(242) = (1.5 +0.004)v

v = 0.64 m/s
