Answer:
0.54 m/s in opposite direction to the other astonaut
Explanation:
The law of conservation of linear momentum states that the sum of initial momentum equals the sum of final momentum. Initially, since both don't move then initial momentum is zero. Momentum, p is a product of mass and velocity,
expressed as p=mv
Finally, considering that the 73000 kg moves backward, the velocity is -0.5 m/s.
68000v+ (73000*-0.5)=0
V=(73000*0.5)/68000=0.5367647058823 m/s
Rounded off, it is 0.54 m/s and moves opposite the direction of the 73000 kg astronaut
Before she let’s go, the pendulum has gravitational potential energy. When the bob releases and goes down, the kinetic energy increases, as it goes up, the kinetic energy decreases. Please mark brainliest answer
Answer:
-3044.848m/s^2
Explanation:
Initial velocity = 15.7 m/s (u)
Final velocity = -14.444 m/s (v) velocity after striking moving opposite direction.
Time = 0.0099 s
Average acceleration :
change in velocity/ total time
= V - U/t
= -14.444 m/s - 15.7 m/s/0.0099 s
= -30.144/0.0099 s
= -3044.848m/s^2
Cerebrum is the largest part of the brain, & it’s composed of right & left hemisphere. It performs a higher function like interpreting touch, vision & hearing, as well has speech, reasoning, emotions, & learning. (Reasoning, speech, & learning all are traits of intelligence, as well as creativity, which is on the left hemisphere of the brain.)
