Assume the angle at which the bounced ball leaves the ground is the same as the angle at which the outfielder threw it as shown in Figure P4.74, but that the ball's speed after the bounce is one-half of what it was before the bounce. Everything you need for your studies in one place. (Relation of Euler-Cauchy Equations to Constant-Coefficient Equations) These two large classes of differential equations have in common that we can solve them "algebraically" without actual integration. it returns 6s later. (a) The time interval during which the ball is in motion is 2R3g. stream I went with the quadratic formula based on the proposed solution of 12(784-s). And then starts falling towards the earths surface. After some time when the entire KE gets nullified, the ball stops. 1/ Yg ln1+ Y / g v 0D. Say a ball is thrown vertically upward with some velocity say v1, which we will consider as the initial velocity for the upward path. The velocity at the highest point is zero as the ball momentarily halts there before starting its downward movement. a. Will the 70 shot travel a greater horizontal distance than the 45 shot? Use the approximate value of g = 10 m/s2. ins.id = slotId + '-asloaded'; Answer (1 of 5): Initial velocity 30m/s If velocity after 2sec =v , where f = -9.8m/sec^2 v= u+ft = 30+(-9.8)*2=30-19.6 = 10.4 After 2 sec velocity will be 10.4 m/sec If the ball is at a hight h Then h = ut +0.5 ft^2= 30*2+0.5(-9.8)(2)^2 Or, h = 60-19.6 = 40.4 m Position of the ball is at . This happens because Potential Energy (PE) is directly proportional to the height of the object. A stone falls towards the earth but the opposite is not observed-why? During this downward displacement, the initial velocity is equal to the final velocity of the upward movement i.e. The ball thrown upwards because during it's descent as it starts to fall back down it's velocity is increasing due to acceleration from gravity hence the greater the distance the greater velocity it will achieve before hitting .
