A trebuchet was a hurling machine built to attack the walls of a castle under siege. A large stone could be hurled against a wall to break apart the wall. The machine was not placed near the wall because then arrows could reach it from the castle wall. Instead, it was positioned so that the stone hit the wall during the second half of its flight. Suppose a stone is launched with a speed of Vo = 25.0 m/s and at an angle of = 39.0°. What is the speed of the stone if it hits the wall (a) just as it reaches the top of its parabolic path and (b) when it has descended to half that height? (c) As a percentage, how much faster is it moving in part (b) than in part (a)?

Several people stand on a bridge over a river. The bridge is not level, so the people are all different heights above the river. Each person throws a stone to the river. a) The first person is 26.8 m above the river and throws her stone with a speed of 16.6 m/s at an angle of 6 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below). How long does it take her stone to hit the water, in seconds? b) The second person is 19.0 m above the river and throws his stone with a speed of 17.1 m/s at an angle of -21.4 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below). What is the range of his stone, in meters? c)The third person is 9.1 m above the river and throws their stone with a speed of 6.5 m/s at an angle of 9.3 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).

Chapter 04, Concept Question 04 You are to launch a rocket, from just above the ground, with one of the following initial velocity vectors: (1) w = 201 + 70j, (2) w = -20i + 70j. (3) w = 20i – 70j . (4) w = -20i – 70j. In your coordinate system, x runs along level ground and y increases upward. In the following questions, you will need to rank these vectors. If multiple vectors rank equally, use the same rank for esch, then exclude the intermediste ranking (i.e. if objects A, B, and C must be ranked, and A and B must both be ranked first, the ranking would be A:1, B:1, C:3). If all vectors rank equally, rank esch as '1" LINK TO TEXT Rank the vectors according to the launch speed of the projectile, greatest first. Vector 1.. V Vector 2 Vector 3 |-- v Vector 4 -- v 1.
