the following questions refer to the following situation.
in a circus parade, a clown standing on a float moving at a constant forward speed drops a fake dumbbell. a child in the bleachers on the sidewalk observes the dumbbell. ignore air resistance.
if the float has a velocity of +vfloat with respect to the ground, what is the velocity of the clown as observed by the child?

question 2

a piece of chalk is dropped by a teacher walking at a speed of 1.5 m/s. from the teachers perspective, the chalk appears to fall

Explanation:

Step1: Analyze Question 1

The clown is on the float. The float has a velocity of +$v_{float}$ with respect to the ground. The clown moves with the float, so the velocity of the clown as observed by the child (inertial - ground - based observer) is the same as the velocity of the float, which is +$v_{float}$.

Step2: Analyze Question 2

The teacher is walking at a speed of 1.5 m/s and drops a piece of chalk. In the teacher's non - inertial frame of reference (moving with the teacher), the chalk has no horizontal velocity relative to the teacher. So, from the teacher's perspective, the chalk appears to fall straight down.

Answer:

Question 1: +$v_{float}$
Question 2: straight down
