Answer:
123.2 m/s after 28s
Explanation:
Vi= 0 m/s
a= 4.4 m/s^2
t=28s
Vf after 28s
To find Vf use your kinematics formula Vf=Vi+at
Vi is Zero so it gets removed and the equation becomes
Vf=at
Simply Plug and Solve
Vf= 4.4(28)
Vf=123.2 m/s after 28s
Flames melt the wax which is a physical change. The wax goes from solid to a liquid but it is still wax just going in different forms when it cools. When wax burns the wax combines with oxygen to form CO2, Carbon Monoxide, Carbon particles, (incomplete burning/oxidation) and water. The burning has broken the bonds in the wax and made a new compound.
The velocity of the object at the end of 3.00 seconds is 29.4 m/s.
Find the initial velocity of an object by dividing the time it took the object to travel the specified distance by the total distance. An object at rest has zero velocity and remains so. Such an object does not change its state of motion unless an unbalanced force acts on it. The velocity of a body at rest must be zero, but the acceleration of a body at rest obviously cannot be zero.
Particles thrown vertically upwards will momentarily stop at the highest point of their movement. In free fall the object is affected only by gravitational acceleration. Acceleration is a non-zero value, so the velocity changes and increases as the object falls. This is because acceleration is defined as the rate of change of velocity with respect to time.
