Answer:

216m

Explanation:

As we know S=ut+1/2at^2

S=6×12+1/2×2×12×12

=72+144

=216 m

A man hits a 50 grams golf ball such that it leaves the tee at an angle of 40o with the horizontal and strikes the ground at the

lukranit [14]

Answer:

Explanation:

Range of projectile R = 20 m

formula of range

R = u² sin2θ / g

u is initial velocity , θ is angle of projectile

putting the values

20 = u² sin2x 40 / 9.8

u² = 199

u = 14.10 m /s

At the initial point

vertical component of u

= u sin40 = 14.1 x sin 40

= 9.06 m/s

Horizontal component

= u cos 30

At the final point where the ball strikes the ground after falling , its speed remains the same as that in the beginning .

Horizontal component of velocity

u cos 30

Vertical component

= - u sin 30

= - 9.06 m /s

So its horizontal component remains unchanged .

change in vertical component = 9.06 - ( - 9.06 )

= 18.12 m /s

change in momentum

mass x change in velocity

= .050 x 18.12

= .906 N.s

Impulse = change in momentum

= .906 N.s .

What is the resultant displacement of the two vectors below

NeX [460]

Answer:

The resultant displacement is 5.8 cm, 31° South of the West axis ⇒ 4th

answer

Explanation:

<u><em>A resultant vector</em></u> is the combination of two or more single vectors

If the two vectors are perpendicular, then

<em><u>The magnitude</u></em> of the resultant vector = $\sqrt{x^{2}+y^{2}}$ ,where

x represents the horizontal vector and y represents the vertical vector

<em><u>The direction</u></em> of the resultant vector is $tan^{-1}\alpha$ , where α

is the angle between the horizontal vector and the resultant vector

Vector 1 is 5 cm due to West-axis

Vector 2 is 3 cm due to South-axis

We need to find the resultant displacement of them

The West and South are perpendicular

The West is the horizontal vector and South is the vertical vector

The magnitude of the resultant displacement s is:

$s=\sqrt{(5)^{2}+(3)^{2}}$

$s=\sqrt{25+9}$

$s=\sqrt{34}=5.8$

The direction of the resultant displacement s is:

$tan^{-1}\frac{3}{5}=31$ ° south of the west (between the west and

the resultant displacement)

<em>The resultant displacement is 5.8 cm, 31° South of the West axis</em>
