Answer:
26.67 m/s
Explanation:
From the law of conservation of linear momentum, the initial sum of momentum equals the final sum.
p=mv where p is momentum, m is the mass of object and v is the speed of the object
Initial momentum
The initial momentum will be that of basketball and volleyball, Since basketball is initially at rest, its initial velocity is zero
Final momentum
The answer is <span>B. the amount of hot soup contained in a bowl. Buoyancy is defined as the upward force exerted by a fluid on an object immersed in that fluid. Buoyancy and density are two factors that affect the downward and upward forces exerted on object that affect its ability to "float" or "sink". Only B does not have anything to do with such forces.</span>
Answer:
event s
Explanation:
the cow gets oxygen from the tree and proceeds to respirate.
The velocity of the car at the bottom of the hill=19.8 m/s
mass= 100 kg
height= h=20 m
Velocity at the bottom=V
Using the law of conservation of energy
potential energy at top = kinetic energy at the bottom
m g h= 1/2 m v²
g h= 1/2 v²
9.8 (20)=1/2 V²
V=19.8 m/s
Thus the velocity of car at the bottom of hill=19.8 m/s
