Impulse from a Time-Varying Force
An object with a mass of 2.0 kg has an initial velocity of 5.0 m/s in the positive x-direction. A net force, which varies with time according to the equation F(t) = (3.0t - 2.0)î N, is applied to the object. What is the direction of the impulse delivered to the object during the time interval from t = 0 to t = 1.0 s?
A
Zero (no impulse)
B
Negative x-direction
C
Positive x-direction
D
Direction depends on the object’s final velocity
