A curious kitten pushes a ball of yarn at rest with its nose displacing the ball of yarn 15.4 cm in 3.00 s. What is the acceleration of the ball of yarn?

Back

3.42 cm/s²

A rock is thrown straight upward with an initial velocity of 24.5 m/s where the downward acceleration due to gravity is -9.81 m/s². What is the rock’s displacement after 1.00 s?

Back

19.6 m
