Question

e session.masteringphysics.com Problem 4.15 MasteringPhysics I of 10 Constant Calculate the acceleration of a 1400-kg car that stops from 36 km/h "on a dime" (on a distance of 1.7 cm). Part A Determine the acceleration of the car Express your answer to two significant figures and include the appropriate units. Enter positive value if the direction of the acceleration is in the direction of the initial velocity and negative value if the direction of the acceleration is in the direction opposite to the initial velocity. Correct

Explanation / Answer

Force, F = m x a

F = 1400 x 2900 = 4.06 x 10^6 N
