Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.

Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

What is the total kinetic energy of a 0.15 kg hockey puck sliding at 0.5 m/s and rotating about its center at 8.4 rad/s

AlexFokin [52]

Answer:

$K=0.023J$

Explanation:

From the question we are told that:

Mass $m=0.15$

Velocity $v=0.5m/s$

Angular Velocity $\omega=8.4rad/s$

Generally the equation for Kinetic Energy is mathematically given by

$K=\frac{1}{2}M(v^2+\frac{1}{2}R^2\omega^2)$

$K=\frac{1}{2}0.15(0.5^2+\frac{1}{2}(0.038)^2.(8.4rad/s^2))$

$K=0.023J$

A car starts from rest and undergoes an acceleration of 4.0 m/s/s for a time of 5.0 s. What is the final velocity of the car?

Kruka [31]

Answer:

20m/s

Explanation:

acceleration=final velocity-initial velocity/time

4.0m/s²=v m/s-0m/s/5.0sec

5.0sec×4.0m/s²=v m/s-0m/s×5.0m/s/5.0m/s

20m/s=v
