A mortar is like a small cannon that launches shells at steep angles. A mortar crew is positioned near the top of a steep hill. Enemy forces are charging up the hill and it is necessary for the crew to spring into action. Angling the mortar at an angle of 0 65.0° (as shown), the crew fires the shell at a muzzle velocity of 148 ft/s. How far d down the hill does the shell strike if the hill d subtends an angle o = 37.0° from the horizontal? Ignore air friction. d = How long will the mortar shell remain in the air? time: S How fast will the shell be traveling when it hits the ground? speed: m/s
A monkey escapes from a zoo and climbs a tree to a height h = 4.00 m. Since she is unable to attract him, the caretaker aims her rifle with a sedative dart directly at the monkey and fires the dart with a speed of vd = 20.00 m/s (see figure). The cunning monkey is released the instant the dart leaves the barrel of the rifle, trying to fall to the ground and escape The caretaker is at d = 10.0 m from the base of the tree. Find the height of the monkey when the sedative dart penetrates the monkey's skin.

Javelin is an Olympic sport where the athlete throws a wood stick a certain horizontal distance, as shown in the image below. Range In this problem we are going to assume no air friction, and assume that the javelin lands at the same height that it is launched from. a) At what angle should a javelinier aim the javelin to hit the largest range (farthest distance) possible? (You can just write down the number.) b) The world's record is held by Jan Zelezny, at 98.48m. Using the angle from part (a), what is the minimum speed at which Zelezny could throw his javelin to reach that distance? 21 tv MacBook Pro G Search or type URL
