force = mass * acceleration = 2 * -9.82 = -19.64 newtons
work done = force * distance = -19.64 * 5.092 metres = -100 joules

An object is thrown vertically upward when does it reach maximum height?
when the object reaches maximum height, the velocity of the object is 0 m/s.It reaches maximum height when the gravity of the body has slowed its velocity to 0 m/s. If there is no gravity and there is no external force acting on it then it will never reach a maximum height as there wont be a negativeaccelerationdemonstrated by newtons first law.Where there is and you have the objects initial velocity then you can use :v^2 = u^2+2.a.sv = Velocity when it reaches Max. height so v = 0u = Initial Velocity (m/s)a = Retardation/ Negative Acceleration due to gravity, -9.80m/s ^2And then the unknown (s) is the displacement, or height above ground, and if everything else is in the right format it should be in metres.
If you throw a ball into the air where will it have the greatest gravitational potential energy?
The ball has the highest gravitational potential energy when it is at its highest point in the air, as that is when it has a velocity of zero and is up the highest.
What is A football kicked off at an angle 20 from the ground reaches a maximum height of 4.7 m What is the initial velocity of the kick?
initial velocity of the kick = 28.06 m/s
When a rocket reaches maximum height what is its velocity?
A model rocket reaches maximum velocity at the point where the thrust from the engine matches the drag from the air, or the point where the thrust goes to zero when the fuel burns out, whichever comes first.
How high can a ball go?
The maximum height of a thrown ball is dependent on the upward portion of the initial velocity. Air friction will slow it somewhat but gravity will cause it to lose most of its upward velocity. The velocity will decrease by 9.8 m/sec for each second of its upward motion, until it reaches zero. At that point, the ball is pulled back toward Earth.
When a football kicked reaches its maximum height how does its speed compare to its initial speed?
When it's at its maximum height its speed will be zero.
How do you measure velocity of a falling object if height is 2m?
Velocity= sqrt(2(distance*gravity))
How do you calculate tak-off velocity of airplane?
peak height = (take off velocity^2)/(2*gravity)
What factors have an effect on the maximum velocity at which a vehicule is able to travel on a curve that has no incline?
weight of the vehicle, height and width of the vehicle, gravity, size of the tires (amount in contact with the ground), and friction
You are standing on top of a 140 foot tall bridge You throw a baseball upward from your shoulder 5 ft above your feet with an initial velocity of 95 footsec What is the maximum height of the baseball?
This problem can be solved simply by using the following equation: Vf^2= Vi^2+2*a*d Vf = 0 at the maximum height Vi = 95 ft/s a = acceleration due to gravity = -32 ft/s^2 Plugging these in gives a maximum height from the beginning of the throw as: d= 141 ft However the ball started from a height of 145 ft so the ball reaches a maximum ht of 286 ft.
How high does sugar cane get?
It reaches a maximum height of 10 to 20 feet
When does a model rocket attain maximum height?
when the vertical component of its velocity is zero.
