Answer:
The height of the object is 5007.4 miles.
Explanation:
Given that,
Weight of object = 200 lb
We need to calculate the value of 
Using formula of gravitational force

Put the value into the formula



We need to calculate the height of the object
Using formula of gravitational force

Put the value into the formula





Hence. The height of the object is 5007.4 miles.
Answer:
Vf = 99.7 m/s
Explanation:
In order to find the final velocity of the car, we will use the third equation of motion. The third equation of motion is given as follows:

where,
a = acceleration of the car = 9.2 m/s²
s = distance traveled by the car = 540 m
Vf = Final Speed of the car = ?
Vi = Initial Speed of the car 1.6 m/s

<u>Vf = 99.7 m/s</u>
That depends on several things that we don't know.
A few of them are:
-- the size of the sample
-- what level of radioactivity was measured at the beginning
-- what's the unit of the 12.5
-- the half-life of the substance involved
Answer:
2.551 m/s
Explanation:
Given:
Boulder is dropped from the cliff
thus,
Initial speed of the boulder, u = 0 m/s
Final speed to be obtained, v = 90 km/h =
=25 m/s
also, in the case of free fall the acceleration of the boulder will be equal to the acceleration due to the gravity i.e g = 9.8 m/s²
Now, from the Newton's equation of motion
v = u + at
where, a is the acceleration = g = 9.8 m/s²
t is the time
on substituting the respective values, we get
25 = 0 + 9.8 × t
or
t =
or
t = 2.551 m/s
