The kinetic energy E of a rocket of mass m, traveling at velocity v is given by the formula E = 12 mv2 Suppose a rocket having mass m = 1.8 is changing velocity over time, and velocity at time t is v(t) = 3.9t2 − 3t. Assuming the mass of the rocket remains constant, what is the kinetic energy when t = 1.7? Enter the answer as a decimal number. Round to two decimal places (as needed).
