A fish swimming in a horizontal plane has a velocity Vi= (4i+j)m/s at a point in the ocean where the position relative to a certain rock is Ri=(10i-4j)m After the fish swims with constant acceleration for 20s, its velocity is Vf=(20i-5j) m/s Then if the fish maintains this constant acceleration, where is it t=25s​

An experiment is designed to test the relationship between the initial height of a basketball before it is dropped to the height of its rebound bounce. the height of the rebound bounce is measured using a scale positioned behind the ball. in the above experiment, which condition would not be controlled? a). the starting height of the ballb). the surface the ball bounces on c). the type of ball d). the method to measure the rebound height of the ball

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.
