Melissa's favorite exercise equipment at the gym consists of various springs. handle grip attached to the free end of a spring to 0.80 m from its unstrained position. The other end of the spring (spring constant 45 N/m) is held in place by the equipment frame. What is the magnitude of t Melissa is applying to the handle grip? A) 29 N B) 36 N C) 42 N D) 54N E) 66 N

Respuesta :

Answer:

option B

Explanation:

given,                                      

spring constant (k ) = 45 N/m            

distance of the spring = 0.8 m                    

Magnitude of the force to handle grip = ?

Magnitude of spring force =

F = k x                                  

F = 45 x 0.8                      

F = 36 N                                                            

The magnitude of spring force is equal to F = 36 N

The correct answer is option B
