Question

Show answer no attempt 33% part (b) how fast v, in meters per second, will the cube be moving when it strikes the second spring?

a) 3 m/s
b) 6 m/s
c) 9 m/s
d) 12 m/s

Answer 1

The speed at which the cube will be moving when it strikes the second spring cannot be determined.

Step-by-step explanation:

To find the speed at which the cube will be moving when it strikes the second spring, we need to calculate the velocity using the information given. From the provided information, we can determine that the initial velocity of the cube is 11.2 m/s and the final velocity is unknown. We will assume that the acceleration is constant. We can use the equation v^2 = u^2 + 2as to find the final velocity.

Given: u = 11.2 m/s, a = unknown, s = unknown

Using the equation, rearrange to solve for the final velocity:

v^2 = u^2 + 2as -> v^2 = 11.2^2 + 2a(s)

We don't have the value of acceleration or displacement, so we can't solve for the exact value of the final velocity. Therefore, we cannot determine the speed at which the cube will be moving when it strikes the second spring. The answer is indeterminate.
