50 points worth. 6. Formula Based Problem: A car is speeding down a highway at 30 m/s. A stray dog runs into the road ahead of the driver. The driver hits the brake decelerating at a rate of 10 m/s. The driver managed to stop the car right as it was about to hit the car. How far away was the dog when the driver first hit the brake?

7. Formula Based Problem: a baseball player hits a ball at a Vox of 20 m/s and a Voy of 20 m/s from a height of 1m. How far did it go before hitting the ground. Assume no air resistance.

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
