Rising fast ball. A batter in a baseball game will sometimes describe a pitch as being a rising ball, termed a hop. Although technically possible, such upward motion would require a large backspin on the ball so that an aerodynamic force would lift the ball. More likely, a rising ball is an illusion stemming from the batter's misjudgment of the ball's initial speed. The distance between the pitching rubber and home plate is 60.5 ft. If a ball is thrown horizontally with no spin, how far does it drop during its flight if the initial speed vo is (a) 36 m/s (slow, about 80 mi/h) and (b) 43 m/s (fast, about 95 mi/h)?

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Rising fast ball. A batter in a baseball game will sometimes describe a pitch as being a rising ball, termed a hop. Although technically
possible, such upward motion would require a large backspin on the ball so that an aerodynamic force would lift the ball. More likely, a
rising ball is an illusion stemming from the batter's misjudgment of the ball's initial speed. The distance between the pitching rubber

m/s (slow, about 80 mi/h) and (b) 43 m/s (fast, about 95 mi/h)? (c) What is the difference in the two displacements? (d) If the batter

Hi, today I had my engineering mechanics 1 test which I completely screwed up. I was quite confident in the uniform circular motion, but I had this problem in my exam which completely confused me. When I read "upward vertical acceleration" my head just start to spin as I couldn't understand what force could cause an upward acceleration. Could you help me with this problem? I bet it is easier than it looks, but still, I am confused about what is asking me and most importantly about the input it is giving me. I don't have my exam paper with me, but on my body diagram, I knew that on the aeroplane were exerted the Force of Contact Fn1 and the Force m1g in the y opposite direction. On the pilot was acting the Force of Contact with the seat of the aeroplane Fn2 and the m2g in the y opposite direction. Here is the problem: During an air show an aircraft comes out of a dive at the bottom of a circular arc at a horizontal speed of 97m/s. In the cockpit the aircraft pilot of mass 58kg…
