Answer:

At v=10\ ms^{-1} energy of the ball will be = 500\ Joules

Step-by-step explanation:

Given:

Mass of ball =10 kg

The table for velocity vs Energy is given.

Velocity(ms^{-1})=0,2,3,6,10

Energy(Joules)=0,20,45,180,E  

Energy is in terms of velocity is given by:

E=\frac{1}{2}mv^2

where m represents mass and v represents velocity.

∴ at velocity = 10\ ms^{-1}

Energy = E=\frac{1}{2}(10)(10)^2

E=5\times100

∴ E =500\ Joules

∴ At v=10\ ms^{-1} energy of the ball will be = 500\ Joules

The classroom outside bag had 5 frisbees in it. If 25% of the outside toys are frisbees, then how many total toys are in the bag
malfutka [58]
So 25%=1/4 so technically you just do 5 times 4 since you need 4 more to have a full 4/4 or full 100% so 5 times 4 is 20 so there are 20 totals toys in the bag
