Determine the radius of curvature p and the time-rate-of-change v of the speed for the positions which are "frozen" during the motion simulation. (The positions are for the times t-0,t-0.8 sec,...
The stories of a tall building are uniformly 10.0 feet in height. A ball A is dropped from the rooftop position shown. Determine the times required for it to pass the 10.0 feet of the first, tenth, and one-hundredth stories (counted from the top). Include the effects of aerodynamic drag. The drag force causes an acceleration component in ft/sec2 of 0.005v2 in the direction opposite the velocity vector, where v is in ft/sec 10.0 A first floor t = sec...
You toss a ball into the air at an initial angle of 40∘40∘ above the horizontal. At what point in the ball’s trajectory does the ball have the smallest speed? (Neglect any effects due to air resistance). at the highest point in its flight just after it is tossed just before it hits the ground halfway between the ground and the highest point on the fall portion of the trajectory halfway between the ground and the highest point on the...
9. The figure below shows the trajectory of a ball undergoing projectile motion. The time t-0s corresponds . Its launch velocity, also called are also indicated in the figure which are X0m and y- 0 m. to the moment just as the ball is launched from position the initial velocity, is g. The other two points along the trajectory corresponding the velocity of the ball at the peak ) it strikes the ground (2) at t How do the speeds...
2/94 An experimental fireworks shell is launched verti- cally from point A with an initial velocity of magni- tude u-100 ft/sec. In addition to the acceleration due to gravity, an internal thrusting mechanism causes a constant acceleration component of 2g in the 60" direction shown for the first 2 seconds of Aight, after which the thruster ceases to function. Determine the maximum height h achieved, the total flight time, the net horizontal displacement from point A, and plot the entire...
