(a) -1.208 m
The position of the particle at time t is given by
where:
is the initial position
is the initial velocity
is the acceleration
Substituting into the equation t=3.70 s, we find the position after 3.70 seconds:
(b) -0.838 m/s
The velocity of the particle at time t is given by:
where
is the initial velocity
is the acceleration
Substituting t = 3.70 s, we find the velocity after 3.70 seconds:
Answer:
well divide 400 by 3 and you should get how fast you're going aka (speed)
Any time that the sign (+ or -) of the acceleration<span> is the same as the sign of the </span>velocity<span>, the object will speed up. If the signs are opposite, the object will slow down. </span>Acceleration<span> is a vector quantity. When either </span>velocity<span> or direction changes, there is </span>acceleration<span> (or deceleration).</span>
(1) friction is the force resisting the relative motion of solid surfaces , fluid layers and material elements sliding against each other.
(2) gravity is a science fiction .
(3) Resistance ::: is a property of a conductor by which the passage of current is opposed causing electric energy to be transformed into heat .
(4) viscosity is the quantity that describes a fluid.
(5)
Answer:
See below
Explanation:
Geostationary satellites are placed in orbit above the equator at an orbital altitude of 35786 km in order to perfectly match the earth's rotation...thus they APPEAR stationary in the sky ..... then your DISH TV antenna (etc) can point in one direction at them for continuous communication. Or.... a spy or weather satellite would be able to look at one section of the earth non-stop
