A hot air balloon is moving at a speed of 10 meters/second in the +x direction. The balloonist throws a brass ball with a veloci

ty of -2
meters/second with respect to himself. If the ball lands after 20 seconds, about how far does it land horizontally from the point at which it was
released?
OA 98 meters
OB. 160 meters
OC. 196 meters
OD. 420 meters

Answer:

160 meters

Relative of speed Vr = 10 -2 = 8 m/s    (horizontal speed)

20 sec * 8 m/s = 160 m      since ball travels 20 sec

A right triangle with the base labeled 40 meters and the height labeled 30 meters. The hypotenuse is a dotted arrow labeled R. W
Pepsi [2]

Answer:

The magnitude of the resultant vector R is 50 meters ⇒ 2nd answer

Explanation:

<u><em>The resultant vector</em></u> is the vector sum of two or more vectors

If the two vectors perpendicular to each other, then the magnitude of

the resultant vector is the square root of the sum of their squares

If x and y are two vectors perpendicular to each other, then the

magnitude of its resultant vector R is:

→ R=\sqrt{x^{2}+y^{2}}

Lets solve the problem

A right triangle with the base labeled 40 meters and the height labeled

30 meters

The hypotenuse is a dotted arrow labeled R

→ The base and the height of the right triangle are perpendicular

→ The hypotenuse is the resultant vector of them

Assume that x represents the base of the triangle and y represents the

height of it

By using the rule above

→ x = 40 m , y = 30 m

→ R=\sqrt{x^{2}+y^{2}}

→ R=\sqrt{(40)^{2}+(30)^{2}}

→ R=\sqrt{1600+900}

→ R=\sqrt{2500}=50

<em>The magnitude of the resultant vector R is 50 meters</em>

4vir4ik [10]
If you assume a) that the elastic limit wont be met, and b) that is a linear elastic material, then
f=kx
40=k.03 or k= 1333N/m

5cm?
force=k*.05=1333*.05=67N

100=kx
x= 100/1333 = 7.5 cm
