Question
What’s the answer for this please?
A tankcar has a mass of 20 Mg and is freely rolling to the right with a speed of 0.75 m/s If it strikes the barrier, determine the horizontal impulse needed to stop the car if the spring in the bumperB has a stiffness (a) k o0 (bumper is rigid), and (b) k = 15 kN/m. - 0.75 m/s O (a) Impulse = 15 kN. s (b) Impulse = o O (a) Impulse = ∞ (b) Impulse = 15 kN. s O (a) Impulse = 15 kN. s (b) Impulse = 15 kN. s O (a) Impulse = 15 kN. s (b) Impulse = -15 kN. s
