Question

A block of mass of 10kg travels in the positive direction along a surface with negligible friction. The block has an initial momentum 18kg⋅ms. The block collides with an object of an unknown mass that is at rest. The force exerted on the block as a function of time is shown on the graph. Which of the following best predicts the speed and direction of the block immediately after the collision?

Option 1: 10 m/s in the positive direction
Option 2: 10 m/s in the negative direction
Option 3: 2 m/s in the positive direction
Option 4: 2 m/s in the negative direction

Answer 1

The question regarding the 10kg block's post-collision speed and direction cannot be accurately answered without the force versus time graph, which is necessary to calculate the change in momentum.

Step-by-step explanation:

The provided information is incomplete for resolving the question regarding the block of mass 10kg and predicting its speed and direction post-collision. To solve this problem comprehensively, we would need the force versus time graph mentioned in the question to calculate the impulse applied to the block. The impulse experienced by the block during collision can change its momentum, which can then be used to find the new velocity. Since the graph is not provided, an accurate prediction of the block's post-collision speed and direction cannot be offered.
