A 1500 kg truck travelling north at 60 km/hr collides with a 1200 kg car moving east at 15km/hr. If the two cars remain locked t
Alenkinab [10]

Answer:

33.33j+6.67i km/hr

Explanation:

From the law of conservation of momentum,

Applying,

mu+m'u' = V(m+m')............... Equation 1

Where m = mass of the truck, m' = mass of the car, u = initial velocity of the truck, u' = initial velocity of the car, V = Final velocity.

Note: let j represent the north, and i  represent the east

From the question,

Given: m = 1500 kg, u = 60j, m' = 1200 kg, u' = 15i

Substitute these values into equation 1

1500*60j+1200*15i = V(1500+1200)

90000j+18000i = 2700V

V = (90000j+18000i)/2700

V = 33.33j+6.67i km/hr

Bone has a Young’s modulus of about
MArishka [77]

Answer:

Explanation:

Bone has a Young’s modulus of about

1.8 × 1010 Pa . Under compression, it can

withstand a stress of about 1.66 × 108 Pa before breaking.

Assume that a femur (thigh bone) is 0.56 m

long, and calculate the amount of compression

this bone can withstand before breakin :).

A scale measures the weight of a light object to be 11.000 lbs ± 0.034 lbs. what is the uncertainty if this same scale is use to
Gre4nikov [31]

The uncertainty of the heavy object if the scale remains constant is 0.24 lbs.

<h3>What is uncertainty in measurement?</h3>
  • This is the error associated in an attempt measure the object accurately.

The percent uncertainty in measuring the light weight object is calculated as follows;

= \frac{0.034}{11} \times 100\%\\\\= 0.309\%

The uncertainty of the heavy object if the scale remains constant is calculated as follows;

= \frac{0.309}{100} \times 78.0 \ lbs\\\\= 0.24 \ lbs
