Please help me answer these PHYSICS questions! If you can, walk me through them. 1. A skateboarder that is initially moving at 0.5 m/s begins to accelerate forward at a constant rate of 0.08 m/s². How long does it take the skateboarder to move 5 m? How fast is the skateboarder moving just as it traveled 5 m?

2. Starting from rest, a car travels down a 1/2 mile road in 25s with constant acceleration. What is the velocity of the car when it reaches 1/2 mile?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
