An object is located 40 cm from a converging lens with a focal length of 20 cm. The lens is 60 cm away from a convex mirror with a focal length of -30 cm, as shown in the figure. Where is the final image formed by this optical system and what is its magnification?
An artillery shell is fired with an initial velocity of 300 m/s at 51.0° above the horizontal. To clear an avalanche, it explodes on a mountainside 47.0 s after firing. Illustrate what are the x and y coordinates of the shell where it explodes, re..
A mountain climber jumps a 3.0m wide crevasse by leaping horizontally with the speed of 8.00 m/s. If the climber's direction of motion on landing is 45 degrees, what is height difference between the two sides of the crevasse? Where does the climbe..
