The Sun is a renewable energy source, which, if used through so-called photovoltaic panels, allows you to significantly reduce the use of fossil fuels. In Italy, 2000 kWh of solar energy is collected every year for each square meter of surface, which is the equivalent of 1.5 "barrels of oil" per square meter.

Taking into account the map, which represents the solar energy available in the
capitals of southern Italy per square meter, determines:
1) how many barrels of oil could be saved in one year;
2) how many barrels of oil are saved annually with a photovoltaic panel
of 5 square meters
installed in Naples. C1

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?
