Question
The kinetic energy E of a rocket of mass , traveling at velocity v is given by the formula
E=1/2mv squared
Suppose a rocket having mass m =1.8 is changing velocity over time, and velocity at time t is v(t) = 3.9t cubed -3t. Assuming the mass of the rocket remains constant, what is the kinetic energy when t = 1.7?
![The kinetic energy \( E \) of a rocket of mass \( m \), traveling at velocity \( v \) is given by the formula
\[
E = \frac{1}{2}mv^2
\]
Suppose a rocket having mass \( m = 1.8 \) is changing velocity over time, and velocity at time \( t \) is \( v(t) = 3.9t^2 - 3t \). Assuming the mass of the rocket remains constant, what is the kinetic energy when \( t = 1.7 \)?
