The potential energy:
E p = m · g · h
m = 25 kg, g = 9.81 m/s², h = 3 m
E p = 25 kg · 9.81 m/s² · 3 m = 735.75 J
Answer:
An object with a mass of 0.5 kg and a velocity of 3 m/s
Explanation:
Momentum = mass * velocity
= 0.5 * 3
= 1.5
Highest value among all.
Hope it helps!!
Answer:
weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. ... Alternatively, weight is the product of an object's mass and either the gravitational field or the acceleration of gravity at the point where the object is located.
Explanation:
Answer:
The length of the resultant vector is 50 inches
Explanation:
Use the Pythagorean theorem to find the answer, since the addition of these two perpendicular vectors will have a magnitude (length) equal to the hypotenuse of the right angle triangle formed by the two:
The length of the resultant vector is 50 inches
by the formula of spring force we know that
here we know that
now we will have
now by similar way if the stretch in spring is 0.25 m
force is given by
so it will require F = 250 N force
