You have a spherical mirror with a radius of curvature of+15cm (so it is concave facing you). You are looking at an object whose size you want totriplein the image, so you can see it better. Where should you put the object? Where will the image be? Will it be real or virtual? (Enter your object distances from smallest to largest. Indicate the location of the image with the sign of your answer.)
A disk with moment of inertia I1 rotates about a frictionless vertical axle with angular speed wi. find the ratio of the final to the initial rotational energy
what is the maximum speed the ball can have. imagine there are no other forces acting on the particle.
Calculate the energy density in the electric field. After the collision, the club head travels (in the same direction) at 46 m/s. Find the speed of the golf ball just after impact.
