A stick of mass F is lying on a frictionless surface. A small ball of mass G and velocity v collides with the stick in the center of the stick a right angle to the rod. The collision is elastic.
a) Where is the axis of rotation for the rod after the collision?
b) What is the angular velocity around the axis of rotation after this collision?
c) What is the velocity of the center of mass of the rod after the collision?
A car of mass 1110 kg travels at a speed of 20 ms-1 along a straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.83. Take the acceleration due to gravity to ..
The brakes are applied to a car traveling on a dry, level highway. A typical value for the magnitude of the car's acceleration is 5.45 m/s2. If the car's initial speed is 33 m/s, how long does it takes to stop and how far does it travel, starting ..
