Why would your weight be different on the moon than on earth?

1 answer:

6 0

First of all, weight isnt really a measurement of how much "stuff" you are made of, mass is. weight is the amount of force you put on the surface you are standing on. because earth has more mass, it has higher gravity which pulls your feet down harder then on the moon where there is less mass, so less graviy

A golfer hits a shot to a green that is elevated 3.20 m above the point where the ball is struck. The ball leaves the club at a

dem82 [27]

Answer:

16.17 m/s

Explanation:

h = 3.2 m

u = 18.1 m/s

Angle of projection, θ = 49°

Let H be the maximum height reached by the ball.

The formula for the maximum height is given by

$H=\frac{u^{2}Sin^{2}\theta }{2g}$

$H=\frac{18.1^{2}\times Sin^{2}49 }{2\times 9.8}=9.52 m$

The vertical distance fall down by the ball, h' H - h = 9.52 - 3.2 = 6.32 m

Let v be the velocity of ball with which it strikes the ground.

Use third equation of motion for vertical direction

$v_{y}^{2}=u_{y}^{2}+2gh'$

here, uy = 0

So,

$v_{y}^{2}=2\times 9.8 \times 6.32$

vy = 11.13 m/s

vx = u Cos 49 = 18.1 x 0.656 = 11.87 m/s

The resultant velocity is given by

$v=\sqrt{v_{x}^{2}+v_{y}^{2}}$

$v=\sqrt{11.87^{2}+11.13^{2}}$

v = 16.27 m/s

Hitman42 [59]

Note : Be careful with speed and velocity, even the formula is same that $v = \frac{x}{t}$

1. If we would like to find the velocity, we must calculate the distance from initial to final, $x_{f} - x_{i} = (delta)x$ ,

2. If we would like to find the speed, we must calculate the total distance that travelled ( $x_{total}$ .

So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.
