*<em>But</em><em> </em><em>if</em><em> </em><em>you</em><em> </em><em>need</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>with</em><em> </em><em>sig</em><em> </em><em>figs</em><em> </em><em>it</em><em> </em><em>should</em><em> </em><em>be</em><em> </em><em>10m</em><em>/</em><em>s</em><em> </em><em>(</em><em>1sf</em><em>)</em><em> </em><em>or</em><em> </em><em>12m</em><em>/</em><em>s</em><em> </em><em>(</em><em>2sf</em><em>)</em>
Explanation:
best answer if it worked
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.

Answer:
just find the answer in Google because I post it into Google
Given:
The frequency of the pendulum ( f) = 0.25 Hz.
Total time (t) = 10 s
Concept: Frequency means, the number of oscillation in one second.
Time period is the required time by pendulum to complete one oscillation.
∵ In 1.0 second, number of oscillations = 0.25
∴ In 10.0 second, number of oscillations = (0.25 ×10.0) / 1.0 = 2.5
Hence, the required number of oscillation = 2.5
