I want to know if i correctly solved the problem.

Homework Statement A pirate ship is on a waterfall above a fort. The height of the waterfall is 200m above the fort. The pirate captain fires a cannon with an initial velocity 40m/s at angle of 40 degrees. If the cannonball makes a direct hit on the fort, how far away(horizontally) was the...

Homework Statement A lost dog travels 30 degrees south of west for 450m. He then smells some food and sprints at 20 degrees east of north for 600m. Homework Equations a) Draw each vector. Label the magnitude and thetas. b)Calculate the vector components c) calculate the magnitude of...

I desperately need some help please

Homework Statement A lost dog travels 30 degrees south of west for 450m. He ten smells some food and sprints at 20 degrees east of north for 600m. a) draw each vector. Label magnitude and theta. b) calculate the vector components c) calculate the magnitude of the dog's displacement...

Thank You

square root of (2sin43)^2 + (2cos43 +12)^2

ok i got 13.53 m/s Is that right?

that is the problem, i can't really draw a vector diagram for this question

It is very hard for me to picture the question in my mind.

cos is the x component and sin is the y?

2sin(43) 2cos(43)?

I get that x is 12 and y is 0, but what should i do to foind components caused by the boy's kicking ?

uhhh i don't quite understand what you are talking about

Homework Statement 1) A boy is floating on a raft in a river. THe water flows at a speed of 12m/s east. The boy's feet kick the water,causing a velocity of 2m/s at an angle of 43 degrees north of east. Using Vector components, calculate the magnitude of the raft's velocity. 2)One vector...
