Answer:
I think A because astroids are stronger than a crash. Hope I helped! :)
Explanation:
Answer:
Explanation:
100 % increase makes an amount 2 times .
44 % increase = 42 MJ
100 % increase = 95.45 MJ
final kinetic energy = 2 x 95.45 MJ
= 190.9 x 10⁶ J
1/2 m v² = 190.9 x 10⁶
.5 x m x 9² = 190.9 x 10⁶
m = 4.71 x 10⁶ kg
= 4710 metric ton .
Answer:
Explanation:
Given that,
Force force acting on the Skater's rocket is 220 N
Resistive force acting on it, F' = 30 N
Mass of Shelby, m = 60 kg
We need to find the acceleration of Shelby. Net force acting on Shelby is given by :
Net force = 220-30
= 190 N
The formula of net force is :
F = ma
a is acceleration of Shelby
So, the acceleration of Shelby is 
Answer: its motion
Explanation: Potential energy is stored energy when an object is without motion, kinetic energy is the energy when a object is in motion.
