Let our experts help you. Its pretty evident that after the upward throw, the velocity of the ball gradually decreases i.e. (b) gradually increases as the ball slows down. Which of these balls, if either, has the greater acceleration due to gravity? 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 . : At t = 0s, the initial velocity of the ball is maximum. 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. a. after how many seconds does the ball strike the ground? Projectile travels greatest possible range when the projectile is thrown at an =45. How long will it be before the ball hits the ground? a negative acceleration was working on the ball. (v)V^2 = U^2 + 2gH..(vi), If a ball is thrown vertically upwards with an initial velocity V0 then here is a set of formula for your quick reference.1) Maximum height reached = H = V02 / (2 g) 2) Velocity at the highest point = 03) Time for upward movement = V0 /g4) Time for downward movement = V0 /g 5) Total time of travel in air = (2 V0 )/g 6) Acceleration of the ball = acceleration due to gravity (g) acting downwards, towards the center of earth [ignoring air resistance]7) Forces acting on the ball = Gravity (gravitational force exerted by the earth)[ignoring air resistance]. 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)? answered 06/15/15, Mathematics - Algebra a Specialty / F.I.T.

The force applied on it is again the gravity and this time its having a positive acceleration i.e. 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 (a) At what time t will the ball strike the ground? -. ins.style.width = '100%'; H = V 02 / (2 g) 2) Velocity at the highest point = 0. s ( t) = 96 t . The velocity with which the ball is thrown upward is \[{V_0}\] and it can be termed as the initial velocity of the ball. 3) Time for upward movement = V 0 /g. . The two questions are not part of the question. Expert Answer. a. velocity is zero and the acceleration is downward. A ball is thrown upward with an initial velocity of 13 m/s. The acceleration is negative because this acceleration is directing downwards while the ball is moving upward.And because of this negative acceleration, the velocity of the ball is gradually decreasing. << /Filter /FlateDecode /Length 144358 >> *?7Gp@[Kao??.?='w 6n3?`ovw>.dcgx|eY{HX Considering the Air resistance or Drag force negligible, the only force acting on the ball is Gravity i.e. At the exact instant that the first ball rolls off the edge, a second ball is dropped from the same height.
