Why was Cassini launched toward Venus if it is going to explore Saturn?
The orbit of Venus is between Earth and Saturn
Venus is needed to reflect the radio signals to the probe
The gravity of Venus will boost the speed of the space probe

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
