The spring in a toy rocket launcher has a spring constant of 13 n/m. how far must you compress the spring to cause it to exert a force of 2.5 n?

Distance, x = 0.19 meters

Explanation:

It is given that,

Spring constant of the toy rocket, k = 13 N/m

Force applied on the spring, F = 2.5 N

We have to find the spring constant of the spring. It can be calculated using Hooke's law as :

F = - kx

x = 0.19 meters

Hence, the spring must be compress to cause it to exert a force of 2.5 N.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
