Amechanic jacks up the front of a car to an angle of 8.0° with the horizontal in order to change the front tires. the car is 3.05 m long and has a mass of 1130 kg. gravitational force acts at the center of mass, which is located 1.12 m from the front end. the rear wheels are 0.40 m from the back end. calculate the magnitude of the torque exerted by the jack.

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

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?
