What is the direction of the tangential speed when a car is driving around a circular curve?

toward the center of the curve
out from the center of the curve
straight ahead, in the direction the car is moving
straight behind, in the opposite direction the car is moving

straight ahead, in the direction the car is moving

Explanation:

when an object is moving around a circular curve, the tangential speed of the object has a direction which is tangent to the curve: therefore, it must go straight ahead, in the direction the car is moving.

On the contrary, the centripetal acceleration of the object (which keeps the object in circular motion) has a direction which is toward the center of the curve.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
