A 70 kg person can achieve the maximum speed of 2.5 m/s while running a 100 m dash. Treat the person as a point particle. a. At this speed, what is the person's kinetic energy? Express your answer with the appropriate units. b. To what height above the ground would the person have to climb in a tree to increase his gravitational potential energy by an amount equal to the kinetic energy you calculated in part A? Express your answer...

Based on your results. did all of the initial gravitational potential energy convert into kinetic energy? If there is a difference between the gravitational potential energy and the kinetic energy, what do you think caused the difference? Did the angle of the track or the mass of the cart have any effect on the data? Explain What were the sources of error m this experiment? How did your hypothesis compare to your conclusion? Hypothesis in winter ski jumping, how would...

Suppose a 0.390 kg ball is thrown at 17.0 m/s to a motionless person standing on ice who catches it with an outstretched arm as shown in the figure below. (a) Calculate the final linear velocity (in m/s) of the person, given his mass is 90.0 kg x m/s 07 (b) What is his angular velocity (in rad/s) if each arm is 3.00 kg? You may treat the ball as a point mass and treat the person's arms as uniform...

Which of the following energy system(s) is (are) independent of orientation/direction? -Kinetic Energy (moving left vs right) -Rotational Kinetic Energy (spinning clockwise vs spinning anti-clockwise) -Spring-Mass Potential Energy (being compressed vs being stretched) -Gravitational Potential Energy (being 2 m above ground vs 2 m below ground) I thought it was kinetic energy and spring mass potential energy but is it also rotational energy?
