Answer 1

Answer:

Explanation:

Discus throw sports event describe a circular path with a velocity of constant megnitude:

=> In a discus throw sports event, athlete holds the hammer or the discus in his/her hand and gives it a circular motion  by rotating his/her own body.

=> If you note carefully, on being released the hammer or discus moves along a straight line tangential to the circular path.

=> This is because once the hammer or discus is released, it continues to move along the direction it was been moving at that instant.

=> It proves that the direction of motion changed at every point when the discus/hammer was moving along the circular path.
