Answer:

a) Vf = 4.95 m/s

b) t = 0.51s

Explanation:

take downwards as positive.

let Vf be the final velocity as the cucumber reach the bottom of the bin and Vi be the initial velocity of the cucumber when they dropped.

a ) from equations of motion:

(Vf)^2 = (vi)^2 +2g×(x - x0) ,

<em>since x0 = 0 m and Vi = 0 m/s.</em>

Vf = \sqrt{2g×(x)}  = \sqrt{2(9.8)×(1.25)} = 4.95 m/s, downwards

therefore, the cucumber will reach the bottom of the bin with a speed of 4.95 m/s.

b) from equations of motion:

Vf = Vi + g×t

Vi = 0 then:

t = Vf/g = 4.95/9.8 = 0.51 s

therefore, the cucumber will take 0.51 seconds to reach the bottom of the bin.

Andru [333]
Hello,

The answer is option B KE=1/2mv^2.

Reason:

In order to calculate the kinetic energy of a object you need to use option B which is the correct formula to find the kinetic energy.

If you need anymore help feel free to ask me!

Hope this helps!

I attached a Diagram for this problem.

We star considering the system is in equlibrium, so

Fm makes 90-(\theta+5) with vertical

Fm makes 70 with vertical

Applying summatory in X we have,

\sum F_x = 0

W+1.4-Fm cos(70)

We know that W is equal to

W= 0.06*100N = 6N

Substituting,

Fm cos (70) = W+1.4N

Fm cos (70) = 6N + 1.4N

Fm = \frac{7.4}{cos(70)}

Fm = 21.636N

<em>For the second part we know that the reaction force Fj on deltoid Muscle is equal to Fm, We can assume also that</em> \beta  = \theta
