Answer:
7m/s
Explanation:
Data obtained from the question include:
K.E (kinetic energy) = 4410J
m (mass) = 180kg
V (velocity) =?
Kinetic energy is the energy an object possess while in motion. It is represented mathematically as:
K.E = 1/2 mv^2
With the above formula, we obtained the velocity the car as follow:
K.E = 1/2mv^2
4410 = 1/2 x 180 x v^2
4410 = 90 x v^2
Divide both side by 90
v^2 = 4410/90
v^2 = 49
Take the square root of both side
v = √49
v = 7m/s
Therefore, the velocity of the car is 7m/s
