"You have been asked to design a "ballistic spring system" to measure the speed of bullets. A spring whose spring constant is k

is suspended from the ceiling. A block of mass M hangs from the spring. A bullet of mass m is fired vertically upward into the bottom of the block. The spring's maximum compression d is measured."
"Find an expression for the bullet's speed vB. Express your answer in terms of the variables m, M, k, d, and constant g."
I've been able to find a few solutions that produce the right result, but none that use the variable g, which MasteringPhysics is requiring. Can anyone help me find a correct equation for the problem that contains the g constant in it?

Answer:

In your question which ask to design a ballistic spring system to measure the speed of bullet. The ask is to find the expression for the bullets speed by using the term given in your question so base on the data you have given and with my calculation the answer is  (M+m)*g*d + 1/2*k*(d1-d)^2

A car starts from rest and accelerates from u seconds until it reaches a speed of 10ms
9966 [12]
Distance = speed* time

10x10^-3 *u + 10x10^-3 * 2u = 125

0.01u + 0.02u = 125

0.03u = 125
u = 4166.66666.... s

acceleration = (final velocity - initial velocity)/time

(10x10-3 - 0)/4167 = 2.3998 * 10^-6 m s-2

Emma is working in a shoe test lab measuring the coefficient of friction for tennis shoes on a variety of surfaces. The shoes ar
Rashid [163]

Answer:

Explanation:

Force of friction = μ N , where μ is coefficient of friction , N is normal force on the body .

a )

Given,

Normal force N = 400 N

Force of friction = 300 N

μ = coefficient of static friction = ?

Putting the values ,

300 = 400 μ

μ = .75

b )

Normal force N = 400 N

Force of friction = 200 N

μ = coefficient of kinetic  friction = ?

Putting the values ,

200 = 400 μ

μ = .50

c ) see attached file .

If Sarah melts 10g of tin. What mass of melted tin would she have at the end of the experiment?​
Nastasia [14]

Answer:

10g

Explanation:

As the Law of Conservation of Mass states that " Mass can neither be created nor be destroyed in a chemical reaction".

Though melting of tin isn't a chemical change, the same logic is applied here...

Hence,

The mass of tin will be 10 g itself...
