A baseball is hit at 30.0 m/s at an angle of 53.00 above the horizontal. Immediately an outfielder runs 4.00 m/s towards the ball and catches the ball at the same height that it was hit. What was the original distance between the outfielder and the batter?
We have a typical student microscope with a rotating platform that allows the user to select from three objective lenses. calculate the highest and lowest magnitude of the overall angular magnifications available
find out the speed with which the pebble strikes the ground when the pebble is fired (a) horizontally, (b) vertically straight up, and (c) vertically straight down
You shine a green laser pointer (%u03BB = 535 nm) on a diffraction grating that contains 1.0 x 10 ^4 lines/cm. how far apart will the zeroth-order and first-order bright spots be
A hand grenade is thrown with a speed of v0 30 m/s, and a 60 degree angle with x-axis, just prior to exploding. Find the velocity of the other piece after the explosion
M1 is five times more massive than M2. One force acts on the hanging mass, but the net force acts on both masses. Once you have the acceleration, you can compute the distance.
define the speed of the particle when the string is parallel to the electric field.
