An insurance company wants people to avoid risks because if the person meets with an accsident the expense of the medicines and treatment should be covered by the insurance company.
Answer:
(C) 40m/s
Explanation:
Given;
spring constant of the catapult, k = 10,000 N/m
compression of the spring, x = 0.5 m
mass of the launched object, m = 1.56 kg
Apply the principle of conservation of energy;
Elastic potential energy of the catapult = kinetic energy of the target launched.
¹/₂kx² = ¹/₂mv²
where;
v is the target's velocity as it leaves the catapult
kx² = mv²
v² = kx² / m
v² = (10000 x 0.5²) / (1.56)
v² = 1602.56
v = √1602.56
v = 40.03 m/s
v ≅ 40 m/s
Therefore, the target's velocity as it leaves the spring is 40 m/s
Answer:
Explanation:
Let's define the variables to proceed with the operations,
So,
The masses
Average distances
Gravitational constant
The formula of the Gravitational Force between the Moon and the Earth would be,
This force is in the direction of the earth.
We perform the same process but now between the Sun and the Moon, like this,
This force is in the direction of the Sun
The net force must be
This in the direction of the Sun.
Answer:
