A meter stick whose mass is 290 grams lies on ice. You pull at one end of the meter stick, at right angles to the stick, with a

katen-ka-za [31]

Answer

given,

mass of the stick = 290 grams = 0.29 Kg

Force on the stick on one side = F = 9 N

force acting perpendicular to stick.

magnitude of acceleration

rate of change of angular momentum is equal to Force

rate of change of angular momentum = 9 N

F = m a

$a = \dfrac{F}{m}$

$a = \dfrac{9}{0.29}$

a = 31.034 m/s²

Direction of motion will in the direction of force application or in the direction of change of velocity

What is the difference between acceleration and linear acceleration?

Akimi4 [234]

Explanation:

Linear acceleration is a type of acceleration of a body along a straight path or line.

Acceleration is defined as the rate of change of velocity with time.

Acceleration = $\frac{Change in velocity}{time}$

There are different types of acceleration .

linear acceleration is used to describe the rate of change of velocity of a body along a straight path with time.
centripetal acceleration is the rate of change of velocity of a body traveling along a circular path with time. It is directed towards the center.
Angular acceleration is the rate of change of angular velocity.

A man stands on a scale in an elevator as shown here. the force of his weight when the elevator is still is fg downward. suppose

Sever21 [200]

When the elevator moves downward, the man weighs less because of the inertia.
Force of Weight:Fg=m×g
Fs=m×g-m×1/4g=m×(g-1/4g)=m×3/4g
If He Went Up you would have to add 1/4g

When you must give something up in order to get something else, it is called...

natali 33 [55]

Opportunity cost refers to what you have to give up to buy what you want in terms of other goods or services. When economists use the word “cost,” we usually mean opportunity cost.
