3. A ball is thrown straight up, reaches a maximum height, then falls to its initial height. Make a statement about the direction of the velocity and the acceleration as the ball is coming down. (1 mark) a) Both its velocity and its acceleration point upward b) Its velocity points downwards and its acceleration points upwards c) Its velocity points upwards and its acceleration points downwards d) Both its velocity and its acceleration point downwards. 4. A man stands on...
A rock of mass 2.0 kg is thrown upwards from the ground and its reaches a height of 15.0 m (it is not the max height!) where its speed is 25.0 m/s. a) Find the work done by gravity up to 15.0 m of upwards displacement. b) Find the rock’s speed as it leaves the ground using the work-kinetic energy theorem. c) Find the max height it reaches
At time t-0 s, 0.80 s later, it reaches its maximum height a rock is thrown vertically upward from the ground. At time t 1.6 s,it passes the top of a tall tower How tall is the tower? Answer: 25 m Check Correct Marks for this submission: 1.00/1.00. How fast is the rock moving as it passes the top of the tower? Answer: Check
A stone is thrown upwards from the top of a building an initial height 11 m above the ground with a velocity of 6 m/s. (4 marks) Calculate i) The maximum height above the building the stone reaches ii) The time it takes the stone to hit the ground iii) The distance the stone travels iv) The displacement the stone undergoes
A stone is thrown vertically upwards with a speed of 20.0 m / s. (a) What is its speed when it reaches 18 meters? (b) What maximum height does it reach?
A rock thrown vertically upward from the surface of the moon at a velocity of24 m/sec reaches a height of s=24t-0.8t^2 meters in t seconds.a) Find the rock’s acceleration and velocity at time t.b) How long does it take the rock to reach its highest point?c) How high does the rock go?d) How long does it take the rock to reach half its maximum height?e) How long is the rock aloft?
A ball is thrown upwards with a speed of 19 m/s. it reaches a hight of 18.4 m above the point of release before it falls back down. Specify down as the positive direction and the initial position as the origin. If the balls position after three seconds is -12.9 meters, what is the distance traveled by the rock? The acceleration due to gravity is 9.8 m/s^2 down. The answer is 23.9 meters, how would i solve this?
A rock is thrown straight up with an initial velocity of 25 m/s. What maximum height will the rock reach before starting to fall downward?
A stone is thrown vertically upwards with a speed of 20.0 m / s. (a) What is its speed when it reaches 18 meters? (b) What maximum height does it reach?
4. A rock is thrown at an angle of 30 degrees above the horizontal and takes a time “T” before reaching its maximum height. a. Draw the picture, insert coordinate system and list the parameters between the initial point and the point at maximum height. Given [T] Determine: b. The initial speed of the rock. c. The horizontal distance the rock travels to reach its maximum height. d. The maximum height the rock attains. e. The speed of the rock...
