Blood is accelerated from rest to 30.0 cm/s in a distance of 1.80 cm by the left ventricle of the heart. (a) make a sketch of the situation. (b) list the knowns in this problem. (c) how long does the acceleration take? to solve this part, first identify the unknown, and then discuss how you chose the appropriate equation to solve for it. after choosing the equation, show your steps in solving for the unknown, checking your units. (d) is the answer reasonable when compared with the time for a heartbeat?

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

Heat up ? and cool down? well im guessing at this one, plz check it first
