Answer:
4m/s approx
Explanation:
Step one
Given data
m1=71kg
m2=65kg
v1=3.4m/s
v2=??
We are required to find the Velocity of the second person
By applying the conservation of momentum principles
P=mv
m1v1=m2v2
Substitute
71*3.4=61*v2
241.4=61v2
Divide both sides by 61
v2=3.95m/s
v2=4m/s approx
Answer:
<h2>
The number of tree is 2</h2>
Explanation:
the diagonal of the rectangular plot of land can be found using Pythagoras theorem (the diagonal is the hypotenuse)
Given
length of land x= 48m
width of land y= 20m
digonal z= ?
substituting the values of x and y into the equation we can solve for z
The diagonal is 52m
Hence since the interval = 22m the number if treee is
The number of trees must be whole numbers , the number of tree is 2
