The force can be calculated by multiplying the mass of the gymnast with her acceleration.
Force = 50 kg × 25 m/s2
Force = 1250 N
A force of at least 1250 N can stop the 50-kg gymnast.
I hope I was able to answer your question. Have a good day.
Answer:
Final velocity = 16 m/s
Total distane travelled = 390 m
Explanation:
We can use equation of motion to solve this:
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 .
