Answer: 24 hours
Explanation: One day is one rotation of the Earth, but it takes the earth 365 days to do one revolution or one year
Answer:
7.5s
Explanation:
Given parameters:
Velocity = 30m/s
Deceleration = 4m/s²
Unknown:
Time it takes for the car to come to complete rest = ?
Solution:
To solve this problem, we use the kinematics expression below:
v = u + at
Since this is a deceleration
v = u - at
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time taken
v - u = -at
0 - 30 = -4 x t
-30 = -4t
t = 7.5s
Responsible because we feel less stressed when others help out with our responsibilities.
They start at 1 meter and after 10 seconds they've moved to 6 meters.
6 - 1 = 5 meters
