Answer: action forc roketorce
reaction force is engine fires
The region where warm and cold air masses meet is called a front
<h2>
Time taken is 0.632 seconds</h2>
Explanation:
Impulse momentum theorem is change in momentum is impulse.
Change in momentum = Impulse
Final momentum - Initial momentum = Impulse
Mass x Final velocity - Mass x Initial Velocity = Force x Time
Mass x Final velocity - Mass x Initial Velocity =Mass x Acceleration x Time
Final velocity - Initial Velocity = Acceleration x Time
Final velocity = 9.9 m/s
Initial Velocity = 3.7 m/s
Acceleration = 9.81 m/s²
Substituting
9.9 - 3.7 = 9.81 x Time
Time = 0.632 seconds
Time taken is 0.632 seconds
Explanation:
63 kg ice skater finishes her performance and crossed the finish line with a speed of 10.8 m/s
Answer:
Explanation:
As we know that moment of force is given as
now we have
now from above formula we have
here we know that
so we have
