A boat is traveling with the current of a river. The current has a velocity of 5 m/s. The boat is moving at 5m/s relative to the river in the direction of the current. To a stationary viewer on the shore the boat appears to be moving?

mimih:

I do not understand what this question is asking me to do?

emmacole:

hmmmmmm same!

amym:

same

Shadow:

Think of it this way. The velocity of the boat relative to the land is equal to the velocity of the boat in the water + the velocity of the current. You effectively get 5m/s + 5m/s It's like when a car passes you on the road at 10m/s, it looks like it's going 10m/ms. But imagine the road is a treadmill, going at 5m/s, so really relative to the ground which is off the treadmill, the velocity of the car appears to be 15m/s.

Shadow:

You're welcome

mimih:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Shadow You're welcome \(\color{#0cbb34}{\text{End of Quote}}\) It was correct, I have more questions about some other physics question, is it possible you can help?

Shadow:

I'm doing some hw rn but you can post them and I'll try answer them quickly

Shadow:

Okay when are they due?

mimih:

A red bouncy ball is dropped from 10 meters high. As it fails a wind is blowing horizontal at the speed of 15 m/s. How far horizontally will the ball hit from the point at which it was dropped? Please round to 1 decimal place. You will enter in units of meters but NUMBER ONLY. A bullet is fired horizontally from a 11.7 m high cliff at a speed of 380.0. What is the distance from the cliff that the bullet will hit the ground below? What would be the landing distance from the base of the 10 m high platform to where the cannonball lands if it is shout out with an initial velocity of 1.8 m/s? Please round to 1 decimal places. What would be the landing distance from the base of the 10 m high platform to where the cannonball lands if the velocity horizontally that it is shout out is 9.6 m/s? Please round to 1 decimal places.

mimih:

well im already past the due date but preferable before next Monday? if possible?

Shadow:

Okay I'll answer them Friday/Sat. I learned this stuff back in high school but I'll have to do some quick review to relearn it. The concept isn't that hard if I recall though, same velocity stuff but you had to do some trig I think.

mimih:

thank you very much, i cannot for the life of me understand physics besides something super basic:(

Hey I kind of forgot about this but I've been out of commission for the past few days. My eye got damaged and I'm resting and trying to heal. Won't be able to help you out here, sorry. Was looking forward to the physics.

Thank you for the help before!
