Give two possible interpretations for each instruction. However, if the cylinder is rotating at angular velocity \Omega, a lift force FFF will arise. EVO AE Homex = 5.86 m Submit Previous Answers Request Answer X Incorrect; Try Again; 3 attempts remaining Provide Feedback. In this case the range is given by. So, the ball strikes the ground after 6 seconds. So we get t = 0 s e c and t = 6 s e c. Here, t = 0 when the ball is at rest and t = 6 s e c is when the ball comes back to the ground after being thrown upwards. ehild has the correct explanation as far as avoiding energy explanations. (Velocity and Acceleration of a Tennis Ball). Solve for maximum altitude, Hmax. As it moves upwards vertically its velocity reduces gradually under the influence of earths gravity working towards the opposite direction of the balls motion. Now the horizontal range of the ball is and time taken by the ball to reach the distance is, Therefore the balls speed at the beak of the path is, Therefore the initial vertical component of the velocity is, Therefore the initial velocity of the ball is, Therefore the maximum height reached by the object is, Projectile travels greatest possible range when the projectile is thrown at an, Therefore the maximum horizontal range of the ball is, Question: A projectile is launched at some angle to the horizontal with some initial speed v. with no bounce (green path)? started 640 ft above ground on an initially upward trajectory. v32 = v22 + 2 g H = 0 + 2 g (v12/2g) = v12i.e. At what time does the ball reach the high point in its flight? 1.
