Step-by-step explanation:

Given

Mass (m) = 1.5 kg

height (h) = 21 m

Acceleration due to gravity (g) = 10 m/s²

Now

Energy = mgh

 = 1.5 * 21 *10

 = 315 joule.

Use d=1/2gt2 and solve for the time one spends moving upward in a 0.6-m vertical jump. Then double it for the "hang time"-the ti

Maksim231197 [3]

Answer:

t = 0.35 seconds

Step-by-step explanation:

We have given the equation:

d=1/2gt²

where,

g = 9.8 m/s²

d = 0.6 m

t = ?

Now put the values in the given formula:

d*2/g = t²

0.6*2/9.8 = t²

1.2/9.8 = t²

0.12245 = t²

Now find the square root of both sides

√t² = √0.12245

t = 0.35 seconds

In the given figure we can determine the coordinate of point M from the graph, we get:

$M=(\frac{d}{2},\frac{c}{2})$

We can also determine the coordinates of point N as:

$N=(\frac{a+b}{2},\frac{c}{2})$

Now, to determine the length of segment MN, we need to subtract the x-coordinate of M from the coordinates of N, we get:

$MN=\frac{a+b}{2}-\frac{d}{2}$

Subtracting the fractions we get:

$MN=\frac{a+b-d}{2}$

Now, to obtain the length of AB we need to subtract the x-coordinate of A from the x-coordinate of B.

The coordinates of A are determined from the graph:

$A=(0,0)$

The coordinates of B are:

$B=(a,0)$

Therefore, the length of segment AB is:

$AB=a$

Now we do the same procedure to determine the segment of CD. The coordinates of C are:

$C=(b,c)$

The coordinates of D are:

$D=(d,c)$

Therefore, CD is:

$CD=b-d$

Now, we determine MN as half the sum of the bases. The bases are AB and CD, therefore:

$MN=\frac{1}{2}(a+b-d)$

Therefore, we have proven that the median of a trapezoid equals half the sum of its bases.
