Given vectors A = xˆ2−yˆ +zˆ3 and B = xˆ3−zˆ2, find a vector C whose magnitude is 9 and whose direction is perpendicular to both

natka813 [3]

Answer:

Vector C = 1.334i + 8.671j + 2k or 1.334x + 8.671y + 2z

Explanation:

The concept applied to solve the question is cross product of vector, AXB since vector C is perpendicular to vector A and B and this is solved by applying the 3X3 determinant method.

A detailed step by step explanation is attached below.

Calculate the power required to accelerate a 1150 kg car from rest to a final velocity of 30 m/s up a 100 m long uphill road wit

DedPeter [7]

Answer:

power required is 90.131 kW

Explanation:

Given data

mass of car (m) = 1150 kg

starting velocity (v1) = 0 m/s

final velocity (v2) = 30 m/s

slope angle = 30 degrees

slope distance = 100 m

to find out

power required

solution

we know the power = work / time

here time is given we have calculate the work

work is for car climb 100 m distance is total sum of potential energy + kinetic energy

and we know car climb 100m at 30 degree slope so vertical distance (h) will be h = 100 sin (30) = 50 m

so now potential energy = mass × gravity × height

potential energy = 1150 × 9.81 × 50 = 564075 J

kinetic energy = 1/2 ×mass × velocity²

kinetic energy = 1/2 ×1150 × ( v2 - v1 )²

kinetic energy = 1/2 ×1150 × ( 30 - 0 )² = 517500 J

now put all value in power formula

power = work / time

power = potential energy + kinetic energy / 12

power = 564075 + 517500 / 12 = 90131.25 W

power = 90.131 kW
