B. a car on a track, a stop watch, and a ruler
Answer:
a) Displacement of the object from t = 0 to t = 3 is 1.5 m
b) Distance of the object from t = 0 to t = 3 is 1.83 m
Explanation:
Velocity, v(t) = t² - 3t + 2
a) Displacement is given by integral of v(t) from 0 to 3.
b) t² - 3t + 2 = (t-1)(t-2)
Between 1 and 2, t² - 3t + 2 is negative
So we can write t² - 3t + 2 as -(t² - 3t + 2)
Distance traveled
Answer:
k = 22.05 N/m
Explanation:
The potential energy of the mass is converted into potential energy of the spring.
Given:
mass m = 0.27 kg
gravitational constant g = 9.8 m/s²
distance falling/ stretching of spring h = 0.24 m
Solving for k:
Answer:
density of liquid 0.848 g/ml
Explanation:
from the information given in the question
mass of water = 34.914 - 25.296 = 9.618 g
volume of pycnometer = volume of water
which will be equal to
mass of liquid =33.485-25.296 = 8.189 ml
density of liquid
=
