A horizontal force of magnitude 6.5 N is exerted tangentially on a Frisbee of mass 32 grams and radius 14.3 cm. Assuming the Frisbee, a uniform disk, is originally at rest and the force is exerted for 0.08 s, determine the angular velocity of rotation about the central axis when the Frisbee is released.
An automobile of mass 1500 kg and a truck of 3500 kg collide at an intersection. What is the velocity (magnitude and direction) of the vehicles immediately after collision
A subatomic particle created in an experiment exist in a certain state for a time of 7.8E-20 seconds before decaying into other particles. calculate the minimum uncertainty involved in measuring the mass of this short-lived particle
