Aball is thrown vertically upward (assumed to be the positive direction) with a speed of 24.0 m/s from a height of 3.0 m. (a) how high does the ball rise from its original position? 29.38 correct: your answer is correct. m (b) how long does it take to reach its highest point? 2.44 correct: your answer is correct. s (c) how long does the ball take to hit the ground after it reaches its highest point? 2.44 incorrect: your answer is incorrect. s (d) what is the ball's velocity when it returns to the level from which it started?

a) 29.36 m

b) 2.44 s

c) 2.57 s

d) 25.117 m/s

Explanation:

t = Time taken

u = Initial velocity = 24 m/s

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s²

b)

Time taken by the ball to reach the highest point is 2.44 seconds

a)

The highest point reached by the ball above its release point is 29.36 m

c) Total height is 3+29.35 = 32.35 m

The ball reaches the ground 2.57 seconds after reaching the highest point

d)

The ball will hit the ground at 25.2117 m/s

we need to know the time interval during which the force acts. impulse of force = momentum change

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
