A person walks 2 miles every day to work, leaving her front porch at 7:00 A.M. and arriving at work at 7:30 A.M. ON the way home
Nataly [62]

Answer:

The displacement is zero miles

Explanation:

The displacement of an object that moves from point A to point B is defined as

d =B-A

Where d is the displacement of the object. The displacement does not depend on the trajectory of the object. It only depends on the linear distance between the end point and the starting point.

In this case we know that the person walks from home to work and then walks from work to home. Therefore, the total displacement is the linear distance between the point where its journey begins and the point where the route ends.

The tour begins on the front porch of your house and ends on the front porch of your house (when you return from work). If we call A to the front porch of the house then the displacement is:

d = A-A = 0

The displacement is zero miles, since the person finishes the journey just where it started (front porch)

6: A body throws a ball vertically up. It returns to the ground after 5 seconds. Find the velocity with which the ball is thrown
Elodia [21]

Answer:

Explanation:

Ball rises and falls in equal periods. Because it goes by same speeds and same route. Therefore t_{rise} = t_{fall} =2.5 s

In free fall and vertical throw movement: x= (1/2).a.t^{2}

Here, we can find the height of the ball

x= (1/2).5.(2.5^{2}) = 15.625 m

From the attaches V-t graphics, x=V.t/2

15.624=V.(2.5)/2

V=12.5 m/s
