Answer #1

3) 2.608 m/s

apply momentum conservation

m1 x u1 +m2 x u2 = m1 x v1 + m2 x v2

1750 x 1.5 + 1450 x 1.1 = 1750 x 0.25 + 1450 x v2

v2= 2.608 m/s

    When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage. In one such accident, a 1750 kg car traveling to the right at 1.40 m/s collides with a 1450 kg car going to the left at 1.10 m/s . Measurements show that the heavier car's speed just after the collision was 0.270 m/s in its original direction. You can ignore any road friction during the collision. Part A What was...

    The top edge of a thin rectangular metal plate with a mass of 2.80 kg is attached to a horizontal rod parallel to the edge of the plate. The plate hangs from this rod and is free to rotate about it without friction. The vertical height of the plate is 45.0 cm. The plate is pulled to the right until it makes an angle of 28.0° from vertical and then released from rest. At the same time, a piece of...
