What is the spring constant? 2.0 N weight is hung from it. A spring is stretched 0.115 m when a Round to ones place N/m k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) 54.5 cm. What is the spring constant? When 4 N are attached, it reaches A spring is hanging empty at 83.4 cm. Hint: make sure to change cm to m Round to ones place N/m k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) 13 N/m a total of .16 m? a spring with a spring constant of What is the force needed to stretch Round to ones place N k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) how high will it be from the top of the table? table. If 6.5 N is applied to the spring hangs 85.4 cm above the surface of a A spring has a constant of 28 N/m Hint: change cm to m Round to ones place m 85.4 cm k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) x Round to ones place F x m k = 2.5 N/m F = 15 N k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) What force is needed to stretch an ideal spring with a spring constant of 120 N/m by 30 cm? N k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) A spring with a spring constant of 600 N/m is used for a scale to weigh fish. What is the mass of a fish that would stretch the spring by 7.5 cm from its normal length? W = mg g = 9.8 m/s2 weight of fish: mass of fish: kg N Do NOT round 1st answer Round 2nd answer to tenth k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) A spring in a pogo stick in compressed 12 cm when a 40 kg girl stands on it. What is the spring constant for the pogo stick spring? W = mg g = 9.8 m/s2 Weight of girl: Spring Constant: Round 2nd answer to hundreds N Do NOT round 1st answer N/m k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) A spring is connected to a wall and a horizontal force of 80 N is applied. It stretches 25 cm, what is its spring constant? N/m k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) A spring stretches 8 cm when a force of 13 N is applied. How far does it stretch when a 26 N force is applied? stretch when 26N force is applied: k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) spring constant: N/m m cm A 7.3 kg mass is placed on a spring with a spring constantof 3400 N/m. How much does this stretch the spring? k : spring constant d : change in F : Force (N) F = kd length (m) (N/m) weight of object: stretch: cm m N Round 3rd answer to tenths Round 2nd answer to 3 places Do NOT round 1st answer W = mg g = 9.8 m/s2 |
