Ok so the equation for momentum is:
v=p/m
So you would do:
7800/1200=6.5
So the answer is:
6.5 m/s
Hope this helps :)
Answer:
false and true is the correct answer
Answer:
Weight = Force = Mass times acceleration of gravity
Explanation:
Answer:
<em>12.5watts</em>
Explanation:
Power = Workdone/Time
Since workdone = Force * Distance
Power = Force *distance/Time
Given
Force = 150N
Distance = 10m
Time = 2 minutes = 120seconds
Required
Power
Substitute the given values into the formula;
Power = 150 * 10/120
Power = 1500/120
Power = 12.5Watts
Hence his power is 12.5watts
