Meriam, Kraige & Bolton — Plane Kinetics of Rigid Bodies: Problem 6_25

6/25 The 1800-kg rear-wheel-drive car accelerates forward at a rate of \( g/2 \). If the modulus of each of the rear and front springs is \( 35 \text{ kN/m} \), estimate the resulting momentary nose-up pitch angle \( \theta \). (This upward pitch angle during acceleration is called squat, while the downward pitch angle during braking is called dive!) Neglect the unsprung mass of the wheels and tires. (Hint: Begin by assuming a rigid vehicle.)
