The mass of lead required to make a 1.00 cm3 fishing sinker is 11.3g.
What is mass?
Mass is a metric used in physics to express inertia, a fundamental characteristic of all matter. A mass of matter's resistance to altering its direction or speed in response to the application of a force is what it essentially is. The change that an applied force produces is smaller the more mass a body has.
Given :
Density of lead = 11.3 g/cm3
Volume of sinker = 1.00 cm3
One of a substance's attributes is density, which is calculated by dividing the mass by the volume. Mathematically:
Density : Mass / volume
therefore after putting the values,
mass= 11.3g

#SPJ4
Answer:
2.41m/s
Explanation:
Given parameters:
Initial velocity = 1.5m/s
Acceleration = 0.275m/s²
Distance = 6.45m
Unknown:
Final velocity = ?
Solution:
To solve this problem, we apply the kinematics equation below:
v² = u² + 2aS
v is the final velocity
u is the initial velocity
a is the acceleration
S is the distance
v² = 1.5² + (2 x 0.275 x 6.45)
v = 2.41m/s
