A body of mass 20kg initially at rest is subjected to a force of 40m for 15sec. Calculate the change in k.e

Explanation:

mass(m)=20kg

velocity(v)=d/t=2.67

k.e=?

now,

k.e=1/2mv^2

=1/2*20*(2.67)^2

=71J

Explanation:kE =10kg(7.3m²/s²)

=73J

Sample Response: The Jaguars would probably have the best finish in a basketball tournament because they have won the most games every season.

Explanation:

As shown on the graph, the Jaguars had the most wins each season compared to the Wolves and the Hawks. In conclusion, you can predict that the Jaguars would probably have the best finish in a basketball tournament.
