@mom.

Answer 2

A group of farmers want to catapult a bale of hay over a wall to a group of hungry cows on the other side. They carefully calculate the necessary angle and aim the cannon at a 46 degree angle. The hay bale just clears the wall as it passes over at the highest point of its trajectory. The top of the wall is 32 m above the release point of the catapult. It is advantageous to draw a diagram and list the known quantities before you start.
a) Calculate the initial velocity in the y-direction.

b) What is the speed of the hay bale just as it leaves the catapult?

c) How long does it take the hay bale to reach the wall?

d) How far from the wall was the catapult placed?

Answer 3

Have you tried to make a drawing

Answer 4

This is a projectile motion problem by the way

Answer 5

The image needs to be fixed

Answer 6

The wall is 32m above the catapult release point

Answer 7

The initial velocity in the y - direction can be calculated using trig functions, any idea how to calculate it?

Answer 8

hm is it cos46
