To go the maximum distance the shell must be fired at an angle of 45 degrees, which means its initial horizontal and vertical velocities are equal; call it v_1. From y=y_0 +v_1 t - (1/2)gt^2 you can set up an equation for the time the shell is aloft. Then use that expression for time in the equation for horizontal motion: x = x_0+v_1 t = 41Km and solve for v_1. Don;t forget that the initial velocity is the vector sum of the initial vertical and horizontal velocity components.

Answer:
The tundra is classified as a cold icy desert. Permafrost is on the ground in the tundra. But the tropical rainforest is wet climate group not like the tundra that is cold and dry. The tundra is plains that can not support trees there is a few bush here and there, but not a lot.
Answer:
2200
Explanation:
The Hubble law states that
v= H × d
where, v = speed, H = Humble constant, d = distance.
Thus
v=22 km/(sec/million ly)×100 million ly
=2200 km/sec.
Answer:
Japan
Explanation:
Early history
The original type of sushi was first developed in Southeast Asia and spread to south China before being introduced to Japan sometime around the 8th century. Fish was salted and wrapped in fermented rice, a traditional lacto-fermented rice dish.
