Question 14 (1 point) When a bus is travelling down the highway and a bug's guts get splattered across the windshield, the bug experiences a different collision time as the bus. True False Question 15 (1 point) Two objects, A and B have the same size and shape and mass Object Alands on concrete while object B lands on a foam pad.Both objects will have the same impulse ,but object B will have a __ collision time and a force of impact. __ a Bigger; bigger Smaller; smaller Bigger; smaller Smaller, bigger

## Step1For question 14, we need to understand the concept of relative velocity and collision time. The bug and the bus are moving at different velocities, but the bug experiences the collision at the same time as the bus. This is because the bug is in the same frame of reference as the bus. Therefore, the bug does not experience a different collision time than the bus.## Step2For question 15, we need to understand the concept of impulse, collision time, and force of impact. Impulse is the change in momentum of an object when a force is applied over a period of time. The impulse experienced by an object is the same regardless of the surface it lands on. However, the collision time and the force of impact can vary depending on the surface. ## Step3When object A lands on concrete, it experiences a smaller collision time and a larger force of impact because concrete is a hard surface. On the other hand, when object B lands on a foam pad, it experiences a larger collision time and a smaller force of impact because foam is a soft surface. This is due to the fact that the foam pad compresses, increasing the collision time and reducing the force of impact.
