Answer:
The distance of the runners from the flag pole is 1.28 miles west of the flagpole
Explanation:
Both the runners will meet at the same time = t
Distance they will cover together = 7 + 1 = 8 miles
Let speed of runner A = v₁ = 5 mph
Let speed of runner B = v₂ = 2 mph
Distance = Speed × Time
v₁t+v₂t = 8
Distance covered by runner A = v₁t = 5× (8/7) = 5.71 miles
Distance of runner A from flagpole = 7-5.71 = 1.28
The distance of the runners from the flag pole is 1.28 miles west of the flagpole.
Answer:
rubber ball
Explanation:
basically friction is caused by little electrical bonds at a molecular level. the ice had more bonds due to it being a cube rather than a ball which has one point of contact. this means less energy is needed to put the ball in motion than the ice cube.
The increase in potential energy is
Explanation:
The gravitational potential energy gained by an object lifted above the ground is given by:
where
m is the mass of the object
g is the acceleration of gravity
is the change in height of the object
For the beam in this problem, we have
m = 330 kg
Substituting, we find its gain in potential energy:
