If I had an object of 5kg, which travels at a constant speed of 5 m/s is moving around a circle of perimeter 5m for 1 second. Obviously its speed would equal to 5 m/s however because its displacement...

3. A force of 40N applied at the end of a wire of length 4m and diameter 2mm produces an extension of 0.24mm. Calculate : (1 mark) i) stress on the wire

Rob has a mass of 75 kg and stands on a frozen lake at rest. Suddenly, Rob’s 45-pound dog comes running across the ice at 4.6 m/s and collides with Rob. How fast does Rob and his dog move together...

A freight car with a mass of 3.5 x 105 kg traveling at 5 m/s connects itself to another identical freight car at rest. What is their final speed together after the collision

A 20-gram rubber bullet traveling at 150 m/s hits a stationary 8.5 kg concrete block. If the bullet bounces off of the block in the opposite direction at 100 m/s, what is the final speed of the concrete...

. An astronaut initially at rest in space fires a thruster pistol that expels 35 grams of hot gas at 875 m/s in front of her. If the astronaut has a total mass of 160 kg while wearing her spacesuit,...
