Falls resulting in hip fractures are a major cause of injury and even death to the elderly. Typically, the hip’s speed at impact is about 2.0 m/s . If this can be reduced to 1.3 m/s or less, the hip will usually not fracture. One way to do this is by wearing elastic hip pads.

A)If a typical pad is 5.0 cm thick and compresses by 2.2 cm during the impact of a fall, what acceleration (in m/s2 ) does the hip undergo to reduce its speed to 1.3 m/s ?

B)What acceleration (in g 's ) does the hip undergo to reduce its speed to 1.3 m/s ?

C)The acceleration you found in part A may seem like a rather large acceleration, but to fully assess its effects on the hip, calculate how long it lasts.

(a).The acceleration is 52.5 m/s²

(b). The acceleration is 5.35 g.

(c). The time is 0.038 sec.

Explanation:

Given that,

Initial speed = 2.0  m/s

Distance = 2.2 cm

Final speed = 1.3 m/s

We need to calculate the acceleration

Using equation of motion

Put the value into the formula

Negative sign shows the deceleration

(b). We need to calculate the acceleration in terms g

The acceleration is 5.35 g.

(c). We need to calculate the time

Using equation of motion

Put the value into the formula

Hence, (a).The acceleration is 52.5 m/s²

(b). The acceleration is 5.35 g.

(c). The time is 0.038 sec.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
