A bike starts from rest and accelerates to a speed of 15 m/s over the course of 5 seconds. The average acceleration of the
bike is m/s2

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

** urgent** the voltage across the primary winding is 350,000 v, and the voltage across the secondary winding is 17,500 v. if the secondary winding has 600 coils, how many coils are in the primary winding? a- 30 coilsb- 583 coilsc- 12,000 coilsd- 332,500 coils

1. jay fills a wagon with sand (about 20 kg) and pulls it with a rope 30 m along the beach. he holds the rope 25° above the horizontal. the rope exerts a 20-n tension force on the wagon. how much work does the rope do on the wagon?
