firecracker breaks up into several pieces, one of which has a mass of 200 g and flies off along the x-axis with a speed of 82.0 m/s. A second piece has a mass of 300 and flies off along the y-axis with a speed of 45.0 m/s. What are the magnitude and direction of the total momentum of these two pieces? 361 kg m/s at 56.3° from the x-axis O21.2 kg m/s at 56.3° from the x-axis O361 kg m/s at 0.983° from the x-axis 21.2 kg m/s at 39.5° from the x-axis 93.5 kg m/s at 28.8° from the x-axis

a) What is the total momentum of this two-astroid system? (Give answer in component form). Don’t forget to include appropriate units in your answers!

Object 1 with a mass of 4.70 kg, moving right at a speed of 7.80 m/s along a frictionless surface, collides head-on with Object 2 with a mass of 3.30 kg moving left at a speed of 10.6 m/s. After the collision, the Object 1 is moving left at 2.40 m/s. 10. What is true about the total momentum before and after the collision? O Equal in magnitude but opposite in direction O Different in magnitude and direction O Equal in magnitude and direction O Different in magnitude but in the same direction

A 0.13 kg baseball has a momentum of p = 11 kg*m/s as it is pitched toward home plate. A 4.2 kg bat swings at the baseball with a momentum of 28 kg*m/s and is in contact with the ball for 0.06 s. Assume the batter doesn't follow through like they should but instead the bat is at rest immediately after being in contact with the baseball (like bunting it). a.What is the magnitude of the velocity of the baseball just before coming in contact with the bat? b.What is the magnitude of the velocity of the baseball immediately after being struck by the bat? c.What is the magnitude of the impulse on the ball?

The force on an object, m, is given by: F = 30t² where F is in Newton and t in seconds. Determine the change in momentum between t = 1.0 s to t = 3.0 s. 140 kg m/s 400 kg m/s 360 kg m/s 340 kg m/s

Question A puck with mass ma= 0.00242 kg moves eastward with speed  va= 1.73 m/s . It then collides with another puck of mass mb= 0.00125 kg and is moving northward with a speed vb = 2.26 m/s After the collision, puck A now moves at 48. 0° north of east, while puck B moves at 17.0° south of east.   A. What are the speeds of the two pucks after collision?

Brad (mass 75.0 kg) and Janet (mass 60.0 kg) are doing a pairs figure skating routine on ice. Brad is moving at 5.63 m/s to the east, and Janet is moving at 7.20 m/s to the north.

What is the pair's velocity after they join hands? 4.47 m/s, 45.7° north of east 2. 5.08 m/s, 42.9° north of east 3. 3.52 m/s, 36.8° north of east 4 6.37 m/s, 52.6° north of east

Two otters are sliding toward each other on a muddy frictionless horizontal surface. One of them, of mass 7.5 kg, is sliding to the left at 5.0 m/s, and the other, of mass 5.75 kg, is moving to the right at 6.00 m/s. They hold fast to each other after they collide. What is the magnitude of the velocity of these otters right after they collide? O 0.116m/s 0.236m/s O 0.441m/s O 0.226m/s
