At t = 0 a car has a speed of 30 m/s. At t = 6 s, its speed is 14 m/s.

What is its average acceleration during this time interval?

During a race, four competitors of the same weight rode identical bicycles for 10 minutes. At 8 minutes, which bicycle was moving with the greatest velocity?

A constant horizontal force F is applied to a 5 kg box on a frictionless horizontal surface. The box starts from rest and moves 12 meters in 5 seconds.

A red cart of mass 4 kg slides to the right on a frictionless track with a velocity of 4 m/s. It collides with the stationary blue cart of mass 1 kg. After the collision, the blue cart has a velocity of 8 m/s.

In your circuit toolbox, you only have a collection of resistors (?1=100 Ω,?2=20 Ω,?3=10 Ω) and some switches that can be open or closed. Construct a circuit filling in all four boxes, such that the equivalent resistance between A and B is 8 Ω.
