Answer: 0.169 (3 s.f.)
Explanation:
Force = 76 N
Spring constant = 450 N/m
Extension/displacement = x
Hooke's law states that: F = kx
Therefore, 76 = 450 X x
76/450 = x
0.169 (3 s.f.) = x
Science can be used to look for other renewable resources than mining for coal
Wait I don't see the question... Can you comment me in it so I can see? I think it's a glitch or something..
Answer:462400joules
Explanation:
Mass=m=800kg velocity=v=34m/s
Kinetic energy=(m x v^2)/2
Kinetic energy =(800x34^2)/2
Kinetic energy =(800x34x34)/2
kinetic energy =924800/2
Kinetic energy =462400joules
