Your answer: I'm positive that the velocity of the ball that was thrown up on its way down will be greater than the ball that was dropped from rest but another person who I posed this question says otherwise that both balls would hit the ground with the same velocity since acceleration is constant for both balls regardless of the height it was dropped from or thrown up, So it is the ball thrown up then? A ball is thrown vertically upward until it reaches a height of 5 yards. Take g= 10 Will the distance traveled by the rock in a 0.1-second interval near the top of its flight be the same as the distance covered in a 0.1-second interval just before it hits the water? It can be proved that the time for the downward movement or the time taken by the ball to fall from the highest point and reach the ground is same as the time required for the upward movement =v1/g, Lets prove it here mathematically:(see the diagram above for downward movement), so, T = v3/g = v1/g (from equation v above) . The velocity of the ball is calculated using the following formula: v=v0+at where v0 is the initial velocity, t is the time taken in seconds, and a is the acceleration due to gravity g. For an initial velocity of 6 m/s and a time of 0.4 seconds, the velocity of the ball is calculated as follows: v=6 m/s+(10 m/s20.4 s)=10 m/s iii)the total time the body spent in the air. 1/ Yg ln1+ Y / g v 0D. A ball is thrown upward with an initial velocity v 0 from the surface of the earth. Just summing up the answer here though we have already gone through this in the section above. The force applied on it is again the gravity and this time its having a positive acceleration i.e. As this acceleration due to gravity (g) is working opposite to the upward velocity we have to use a negative sign in the formula below, used for the upward movement of the ball. (ignoring air resistance), As the ball reaches the maximum height now it starts its free-fall towards the earth. 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. so the velocity is not necessarily increasing. The important formulas and pointers for vertical motion include 1> the maximum height reached, 2> time required for up & down movement, 3> acceleration of the ball at different points, 4> the velocity of the ball at different instances, 5> forces acting on the ball, 6> formula or equation of vertical motion 7> Kinetic energy and potential energy of the ball in a vertical motionif(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'physicsteacher_in-box-4','ezslot_4',148,'0','0'])};__ez_fad_position('div-gpt-ad-physicsteacher_in-box-4-0'); We will find all these in this post. ), A bullet is fired horizontally with an initial velocity of 700 m/s at a target located 300 m from the rifle.
