Answer:
the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is 360 m/s
Explanation:
The computation of the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is as follows:
The ball momentum is
As there is a similar momentum
So,
Hence, the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is 360 m/s
To develop this problem we will use the linear motion kinematic equations. To find the time, we will use the information given on the y axis, which will allow us to find the time it takes to complete the route. With this time and the speed given in the horizontal direction, we can calculate the total distance traveled in that direction. Consider the motion of dog along the Y-direction
Using the equation,
Along the x-direction
Horizontal Displacement,
Therefore the dog goes before splashing down a distance of 2.975m
