2. A 1423-kg car is moving along a level highway with a speed of 26.4 m/s. The driver then slams her foot on the brakes where she is only moving with a speed of 10.2 m/s so she doesn't spin out over black ice that she sees ahead of her.

A: predict whether the total mechanical energy of the car is conserved or not, explain.

B: determine the magnitude of thermal energy that is produced as a result of breaking so hard.

What is magnetic flux? explain faraday's law of induction.

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
