A block weighing 460 g slides along a frictionless track at a speed 8.1 cm/s. It then attaches to a spring-bumper with an electromagnetic device so that the block attaches to the bumper. The bumper has a mass of 131 g, and the spring has a stiffness of 1320 kg/s2 and an equilibrium length of 8.1 cm. After the spring compresses and returns to its original length, the magnet turns off and the block launches off again, conserving energy. An Aggie does not Lie, Chegg, or Steal, or tolerate those who do. (a) How fast is the block just after it attaches to the paddle? 0.063 m/s Correct: Your answer is correct. (b) What is the maximum compression of the spring before the block turns around? 0.00133 m Correct: Your answer is correct. (c) How fast is the block moving after it launches off the paddle?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
