The forms of kinetic energy are motion, heat, sound and light.
So according to your options, I choose D) Sound energy.
The force of gravity between Earth and Mars will decrease.
The gravitational law is given as-
F = G mM/r²
here, m= mass of rocket
M = mass of earth
r = distance between earth and rocket
So, as rocket takes off from earth and fly towards mars then the distance starts to increase between earth and rocket, and the gravitational pull between them starts to weaken. Then a point will reach when rocket will far from gravity of earth and could probably enter the gravity of Mars.

Answer:
Explanation:
Let the velocity of projection be V .
component of velocity in vertically downward direction = v cos 44.1
component of velocity in horizontal direction = v sin 44.1
s = ut + 1/2 gt²
611 = v cos 44.1 x 5.4 + 1/2 x 9.8 x 5.4²
= 611 = 3.88 v + 142.88
v = 120.65 m /s
b )
horizontal component of velocity of projectile = v sin 44 .1 = 120.65 sin44.1
= 83.96 m /s
horizontal displacement = 83.96 x 5.4 = 453.38 m
c ) horizontal component will remain unchanged so horizontal component
= v sin 44 .1 = 120.65 sin44.1
= 83.96 m /s
d ) velocity of projectile just before striking the ground
v = u + gt
= v cos 44.1 + 9.8 x 5.4
= 120.65 xcos 44.1 + 9.8 x 5.4
= 86.79 + 52.92
= 139.71 m /s
Answer:
50 Kilograms Force (kgf) = 50 Kilograms Force (kgf)
100 Kilograms Force (kgf) = 100 Kilograms Force (kgf)
150 Kilograms Force (kgf) = 150 Kilograms Force (kgf)
200 Kilograms Force (kgf) = 200 Kilograms Force (kgf)
