A stone is thrown horizontally with an initial velocity of 20m from the top of a building 90m high. Find the horizontal range of the stone. Calculate also the velocity with which the stone strikes the ground. A. 84.8 m; 46.9m/s, 64.7° B. 45.0 m; 5.83m/s, 6.1° C. 30.0 m; 43.67m/s, 30° D. 23.5 m; 24.7m/s, 20° m

i need the answer to this too but idk it ; -;

true tan speed = ang vel x radius

at right angles to each other

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
