Answer:
Mass = 2.4 kg
Explanation:
KE = 1/2mv^2Where m is the Mass(kg), and v is the velocity(m/s)We're trying to find the mass so we manipulate the formula for kinetic energy to:m = 2KE/v^2Substitute with the given values:m = 2(1500J)/(35m/s)^2m = 2.448979592 kgFollowing the rules of significant figures, the answer is:m = 2.4 kgHope that helped!

Answer:
Mass = 2.4 kg
Explanation:
KE = 1/2mv^2
Where m is the Mass(kg), and v is the velocity(m/s)
We're trying to find the mass so we manipulate the formula for kinetic energy to:
m = 2KE/v^2
Substitute with the given values:
m = 2(1500J)/(35m/s)^2
m = 2.448979592 kg
Following the rules of significant figures, the answer is:
m = 2.4 kg
Hope that helped!
