A 2kg ball with initial speed 2m/s vertically downwards falls a distance of 4m if the air resistance does -20J of work on the ball, what is it's final speed assume only gravity and air resistance act on the ball. ANSWER is 8m/s How did you get that ANSWER, THANKS.
Alright
Dude, If that worked for you... dont forget to give THUMBS UP.(that
will work for me!)
If I missed something feel free to leave a comment.
atleast before giving downvote.

A ball is thrown vertically downwards with a speed 7.3 m/s from the top of a 51 m tall building. With what speed will it hit the ground, in units of m/s? Assume that air resistance is negligible Glue the answer as a positive number
Question 8 1pts A ball is thrown vertically upward with an initial speed of 20 m/s. Two seconds later a stone is thrown vertically from the same initial height as the ball) with an initial speed of 24 m/s. At what height above the release point will the ball and stone pass each other? The acceleration is 9.8 m/s in the downwards direction 17 m E E 21 m
2/13 A ball is thrown vertically upward with an initial speed of 80 ft/sec from the base A of a 50-ft cliff. Determine the distance h by which the ball clears the top of the cliff and the time t after release for the ball to land at B. Also, calculate the impact velocity UB. Neglect air resistance and the small horizontal motion of the ball. 50 Uo Problem 2/13
A ball is thrown vertically upwards at a speed of 15m/s at the edge of a 20m deep well. The ball is released at a height of 2m above ground level. How high does the ball rise above ground level? If the ball on its downward path falls down the well, how many seconds elapse between releasing the ball and it striking the bottom of the well? Assume that the downward acceleration is 9.81 m/s2 .
A ball is thrown vertically upwards with an initial velocity of 27.0 m/s. Neglecting air resistance, how long is the ball in the air? Submit Answer Tries 0/99 What is the greatest height reached by the ball? Submit Answer Tries 0/99 Calculate the first time where the ball has half of its initial velocity
A 0.44-kg ball is thrown vertically upward with an initial speed of 16.5 m/s. What is the kinetic energy of the ball when it has travelled three-quarters of the distance to its maximum height?
A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...
9. A golf ball rolls off a horizontal cliff with an initial speed of 11.4 m/s. The ball falls a vertical distance of 15.5 m into a lake below. (a) How much time does the ball spend in the air? (b) What is the speed v of the ball just before it strikes the water? Provide your work below, and you must draw a diagram of the problem.
11 and 17 Question 17 2 pts A and B can both walk at a speed 2.4 m/s and run at a speed 5.5 m/s. They start off together to go a distance 65 m. A walks for one half of the time it takes him to reach the distance, and runs for the remaining half the time. B, on the other hand, walks for half the distance, and runs for the remaining half the distance. Calculate how much sooner...
A 0.36-kg ball is thrown vertically upward with an initial speed of 12.5 m/s. What is the potential energy of the ball when it has travelled two-thirds of the distance to its maximum height? (Use the launch point to be the zero reference point of measurements of the heights)
