Answer:
65 miles
Explanation:
The distance travelled till 150 miles is
260 - 150 = 90
But as he walks back although his distance increase his displacement from initial point decrease.
Distance moved from 150 mile post to 175 mile post is
175 - 150 = 25
As he walks backwards in second time in consideration with first time to calculate the displacement we need to substract 90 from 25,
So displacement is 65 miles
You just have to simpy add the vectors together. Draw a picture to help you. Your verticle run is a vector that has a magntiude of 22m along the x axis with an angle of 0, and your climb has is a vector with a magnitude of 4.8 along the y axis and an angle of 90 degreed with respect to the x axis therefore add all of the x components and y components. you will find that the resultant vector has a xcomponent of 22m and a y component of 4.8m so draw a graph the point will be (22,4.8) and then you can simply measure the angle.
Answer:
The potential energy of the bowling ball will be mgh
Explanation:
Let the mass of bowling ball =m
The height of building on which bowling ball sits=h
So,
The potential energy of the bowling ball =P.E.= mgh
