A car and a heavy truck roll down a hill and reach the bottom at the same speed. Compared with the momentum of the truck, the mo

Answer:

A. less

Explanation:

The momentum of an object is directly proportional to it mass and velocity. It is the product of mass and velocity of the object. Given as

$Momentum (p) = Mass (m) \times Velocity (v)$

So the momentum of car,

$p_{c} = m_{c}\times v_{c}$

Momentum of truck,

$p_{t} = m_{t}\times v_{t}$

We know that, mass of car is less than that of truck and velocity of the two are same. It is implied that, momentum of car will be less than that of truck.

A person walks from her home at position O to position F by taking a path that is comprised of three displacement vectors travel

lidiya [134]

Answer:

Explanation:

A = 155 m at 25° North of west

B = 92 m due north

C = 64.7 m at an angle 50° East of north

Write the displacements in the vector form

$\overrightarrow{A} = 155\left ( Cos25\widehat{i}-Sin25\widehat{j} \right )$

$\overrightarrow{A}=140.5\widehat{i}-65.5\widehat{j}$

$\overrightarrow{B}=92\widehat{j}$

$\overrightarrow{C} = 64.7\left ( Cos50\widehat{i}+Sin50\widehat{j} \right )$

$\overrightarrow{C} = 41.6\widehat{i}+49.6\widehat{j}$

(a)

$\overrightarrow{A}.\overrightarrow{C}=\left ( 140.5\widehat{i}-65.5\widehat{j} \right ).\left ( 41.6\widehat{i}+49.5\widehat{j} \right )$

$\overrightarrow{A}.\overrightarrow{C} = 2602.55$

(b)

$\overrightarrow{A}\times \overrightarrow{C}=\left ( 140.5\widehat{i}-65.5\widehat{j} \right )\times \left ( 41.6\widehat{i}+49.5\widehat{j} \right )$

$\overrightarrow{A}\times \overrightarrow{C}=9679.55 \widehat{k}$
