5. A ball is thrown with enough speed straight up so that it is in the air several seconds. (a) What is the velocity of the ball when it gets to its highest point? (b) What is its velocity 1 s before it reaches its highest point? (c) What is the change in its velocity during this 1-s interval? (d) What is its velocity 1 s after it reaches its highest point? (e) What is the change in velocity during this 1-s interval? (f) What is the change in velocity during the 2-s interval? (Careful!) (g) What is the acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity?

Every word problem, there should be a conclusion. therefore add a conclusion to the following answer. "(a) The velocity of the ball at its highest point is 0 m/s. This is because at the highest point, the ball stops moving upwards and is about to start falling downwards. (b) The velocity of the ball 1 second before it reaches its highest point depends on the initial speed and the acceleration due to gravity. The acceleration due to gravity is approximately 9.8 m/s². So, if we denote the initial speed as v0, then the velocity 1 second before the highest point is v0 - 9.8 m/s. (c) The change in velocity during this 1-second interval is the final velocity minus the initial velocity, which is (v0 - 9.8 m/s) - v0 = -9.8 m/s. (d) The velocity of the ball 1 second after it reaches its highest point is -9.8 m/s. This is because the ball has started to fall and is accelerating downwards due to gravity. (e) The change in velocity during this 1-second interval is the final velocity minus the initial velocity, which is -9.8 m/s - 0 = -9.8 m/s. (f) The change in velocity during the 2-second interval is the final velocity after 2 seconds minus the initial velocity, which is (-9.8 m/s) - (v0 - 9.8 m/s) = -19.6 m/s. (g) The acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity is -9.8 m/s². This is the acceleration due to gravity, and it is always acting on the ball, regardless of its velocity."

1. A marble rolled off of a 1-m high tabletop with an initial horizontal velocity of 10 m/s.a) Determine its final velocity.b) How much time will it take for the marble to hit the floor?c) How far will the ball head forward before reaching the floor?2. A ball is hurled from a horizontal ground with a speed of 45 m/s at an angle of 35 0 from thehorizontal.a) What is the final horizontal velocity of the ball after 3.5 seconds?b) How much time will it take for it to reach its highest point?c) How much time will it take for it to reach the ground?d) What is the maximum height reached by the ball?e) What is the maximum horizontal distance covered by the ball?

An object is thrown vertically upwards with an initial velocity of m/s. (take g=10m/s2 Find –(innotebook)-(i) time taken to reach maximum height(ii) maximum height reached(iii) velocity after 5 seconds

A ball is thrown vertically upward with a velocity of 49 m/s. calculate:(a) The maximum height to which it rises.(b) The total time it takes to return to the surface of the earth. (Take g=9.8m/s2)

Which of the following statement is correct for the speed of a ball after it is thrown upward into the air.  1 pointdecreases and then increasesdecreasesincreasesincreases and then decreases
