Question:
A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J. What is the mass of the soccer ball?
Answer:
A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J.The mass of the soccer ball is 0.4 kgs. This answer is derived from the formula
K=1/2 MV^2.So velocity and kinetic energy are given from that mass of the ball is calculated.By substituting the values 500=1/2*M*50*50 which gives M=0.4 Kgs.
From the answer and question examples above, hopefully, they could guide the student sort out the question they had been looking for and remember of each thing declared in the answer above. Then will be able to have some sharing in a group discussion and also study with the classmate in connection with the topic, so another student also obtain some enlightenment and still keeps up the school learning.
