A projectile is fired with an initial speed of 65.2 m at an angle of 34.5? above the horizontal on a long flat firing range. Determine:
(a) The maximum height reached by the projectile.
(b) The total time in the air.
(c) The total horizontal distance covered (that is, the range).
(d) The velocity of the projectile 1.50 s after firing.
An airtight box has a removable lid of area 2.0 10-2m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 0.75 x10^5Pa. The inside of the box is completely evacuated. What is the magnitude of force nece..
