Answer:

Height after 3 seconds is 68 ft

Explanation:

Using the given equation

h=2+70t-16t^2,

and replacing t=3 in it

h=2+70(3)-16(3)^2

h=68 ft

The ball height 3 seconds after kicked it is 68 ft

Place the single weight with a known mass on the spring and release it. Eventually, the weight will come to rest at an equilibri
aliya0001 [1]

Answer:

X=m*g/K

Explanation:

Since the elastic force of the spring is balancing the force of gravity:

Fe = m*g

Now, on the spring by Hook's law, the magnitude of the elastic force will be:

Fe = K*X     where K is the elastic constant of the spring and X is the distance the spring is strectches measured from its original lenght to its current length.

Replacing this value:

K*X = m*g   Solving for X:

X = m*g/K    This value is directly proportional to the object's weight and inversely proportional to the spring's constant.

What is the potential energy of a 150 kg diver standing on a diving board that is 10 m high? The potential energy is J
iris [78.8K]

The formula for potential energy would be PE = mgh Where: m is the mass; g is the acceleration due to gravity, and h would be height. So plugging in the data: PE = 150kg × 9.8 m/s^2 × 10m = 14700 Joules would be the potential energy for this problem. <span>
