part 1: you are on a mystery planet, what you know is that from a height of 10.0 meters, a dropped ball takes 0.88 seconds to hit the ground.
a. list givens
b. show your calculation for g
c. identify your mystery planet using the chart above.
d. determine the final velocity of the ball before striking the ground.

use these forumlas
d=vot +1/2 at^2
vf^2=vo^2 + 2ad
a+(vf -vo) /t

a)

The given quantities are:

is the vertical distance covered by the ball

is the time it takes for the ball to reach the ground

is the initial velocity of the ball

is the acceleration of gravity

is the final velocity of the ball

b)

In order to find the acceleration of gravity, we use the following equation:

Where

t = 0.88 s

d = 10.0 m

Solving for a,

c) Jupiter

The value which is closer to the value calculated is the value for Jupiter, which is 25.95, so the planet must be Jupiter.

d) 22.7 m/s

We can find the final velocity of the ball before striking the ground by using the equation

where

d = 10.0 m

Solving for v,

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
