Answer:
(a)7.48331 Km
(b) Directly above the tomb
(c) 12.53 degrees
Explanation:
Given that the distance is 3.5 Km, converted to meters we obtain 3500 m
Using the formula
where s is the distance and t is time, taking acceleration due to gravity as 9.8 then
t = 26.72 sec
We know that speed=distance/time hence to get the distance in part (a)
Distance=Speed*time
280 *26.72 = 7483.31 m converted to Km we obtain 7.48331 Km
(b)directly above the bomb
(c)
Answer:
The moon is 1,079.4 mi.
Mars is 2,106.1 mi
Multiply your weight by the moon's gravity relative to earth's, which is 0.165. Solve the equation. In the example, you would obtain the product 22.28 lbs. So a person weighing 135 pounds on Earth would weigh just over 22 pounds on the moon
Being that Mars has a gravitational force of 3.711m/s2, we multiply the object's mass by this quanitity to calculate an object's weight on mars. So an object or person on Mars would weigh 37.83% its weight on earth.

Noble Gases (He, Ne, Ar, Kr, Xe, Rn) don't form compounds because they're nonreactive as they have full valence shells (the outermost electron shell).
Answer:
the impulse is 14 kg-m/s and the net force applied is 14000 N
Explanation:
Given that,
The mass of a baseball, m = 0.14 kg
Initial velocity of the baseball, u = -40 m/s
Final velocity, v = 60 m/s
Time, t = 0.001 s
We need to find the impulse and average net force applied to the ball by the bat.
Impulse = change in momentum
i.e.
J = m(v-u)
J = 0.14 × (60-(-40))
J = 14 kg-m/s
Now,
J = Ft
F is average force applied to the ball
So,
So, the impulse is 14 kg-m/s and the net force applied is 14000 N.
