The kinetic energy E of a rocket of mass m, traveling at velocity v is given by the formula E = //mv² Suppose a rocket having mass m =2.0 is changing velocity over time, and velocity at time t is v(t) = 2.5t²-2.6t. Assuming the mass of the rocket remains constant, what is the kinetic energy when t = 1.5? Enter the answer as a decimal number. Round to two decimal places (as needed).

Question
The kinetic energy E of a rocket of mass m, traveling at velocity v is given by the formula E = //mv² Suppose a rocket having mass m =2.0 is changing velocity over time, and velocity at time t is v(t) = 2.5t² -2.6t. Assuming the mass of the rocket remains constant, what is the kinetic energy when t = 1.5? Enter the answer as a decimal number. Round to two decimal places (as needed).
