Work and energy?
This is the problem i dont know how to get the answers?
Answer:
1.213.5 N-m or J
2.2.08m
3.0.40 N
4.0.40 Nm or 0.40 J
Explanation:
1. Work=Force x Distance
Work= 30.5N x 7m = 213.5 N-m or J
2. Joules = Newton-meter
Distance = work / force
distance = 25 N-m /12m = 2.08m
3. Force = Work / Distance
Force = 10Nm/25m =0.40 N
4. 100cm=1meter
20cm x (1m÷100cm)= 0.20m
work= force x distance
work = 2N x 0.20m = 0.40 Nm or 0.40 J
