Question

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

Answer 1

option B

Step-by-step 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
