Hello!
An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object ?
We have the following data:
KE (Kinetic Energy) = 480 J
m (mass) = ? (in Kg)
v (speed) = 8 m/s
Formula to calculate kinetic energy:
Solving:
Answer:
b) 15 kg

The graphed function is _____________.
Answer:
The graphed function is Nonlinear
Going at the speed he believes he can go, Noah will be able to finish the race in 8.34 hours.
First thing to do is to find out the speed Noah can ride at.
Speed = Distance / Time
The time should be in hours because the proper convention is miles per hour.
= 160 / 60 minutes
= 2.67 hours
Speed = 32 / 2.67
= 11.99 miles per hour
Going at 11.99 miles per hour, he will finish a 100 mile race in:
= Distance / Speed
= 100 / 11.99
= 8.34 hours
In conclusion, Noah will finish the race in 8.34 hours.

Answer:
let time for the race be y minutes
If 32 miles =160 minutes
then 100 miles =y minutes
Cross multiply: (100 miles*160 minutes) = 32 y
y = (100*160)/32 =500
time for the race = 500 minutes
Step-by-step explanation:
The fact family for the numbers 15, 5, and 3 includes the multiplication facts 5 * 3 = 15 and 3 * 5 = 15, and the division facts 15 ÷ 5 = 3 and 15 ÷ 3 = 5.
The fact family for the numbers 15, 5, and 3 consists of four related multiplication and division facts. For multiplication, we can write 5 * 3 = 15 and 3 * 5 = 15. For division, we can write 15 ÷ 5 = 3 and 15 ÷ 3 = 5. These equations represent how the numbers 15, 5 and 3 relate to each other in both multiplication and division.
