Answer:
Explanation:
Given the following data;
Mass = 2kg
Energy = 50J
Height = 10m
To find the speed
Kinetic energy can be defined as the energy possessed by a body due to its motion.
K.E = ½mv²
Substituting into the equation, we have;
50 = ½*2*v²
V² = 50
Taking the square root of both sides, we have;
V = 7.07m/s
