I’m confused about this question
Answer:
find the sum of the inital and final velocitys and divide by 2 to find the average
Potential Energy= 24m * 14kg * 9.8N/kg = 3292.8J
Answer:0kgm/s
Explanation:
Momentum before collision=momentum after collision
Since the momentum of the two blocks have positive sign, it means they are moving in thesame direction
Therefore we use the formula
Momentum (A)+momentum (B)=Momentum (A)+momentum (B)
25+35=60+momentum (B)
60=60+momentum (B)
Momentum (B)=60-60
Momentum (B)=0kgm/s
