Explanation:
Kinetic energy is the energy that the body possesses by virtue of its motion.
The formula for Kinetic energy is given by
Using this formula let us find kinetic energy for the bodies given and find out which is the greatest
A) KE =
B) KE =
C) KE =
D) KE =
Comparing these we find that 9mv^2 is the highest.
Hence option C is the answer.
Answer:
one-third of its weight on Earth's surface
Explanation:
Weight of an object is = W = m*g
Gravity on Earth = g₁ = 9.8 m/s
Gravity on Mars = g₂ = g₁
Weight of probe on earth = w₁ = m * g₁
Weight of probe on Mars = w₂ = m * g₂ -------- ( 1 )
As g₂ = g₁/3 --------- ( 2 )
Put equation (2) in equation (1)
so
Weight of probe on Mars = w₂ = m * g₁ /3
Weight of probe on Mars = m * g₁ =
w₁
⇒Weight of probe on Mars = Weight of probe on earth
