Answer:
the acceleration of the car is -5 m/s².
Explanation:
Given;
initial velocity of the car, u = 50 m/s
time of motion, t = 6 s
final velocity of the car, v = 20 m/s
The acceleration of the car is calculated as;
Therefore, the acceleration of the car is -5 m/s².
Answer:
Work done by battery will be equal to 10.238 J
Explanation:
We have given ideal an ideal battery with ideal voltage V = 24 volt
Constant current
Resistance will be equal to
Time is given t = 3 minutes = 3×60 = 180 sec
We have to find work done by battery
Work done is equal to
So work done by battery will be equal to 10.238 J
The formula for getting the density of an object is
density = mass/volume = ρ = m/v
mass =42 kg
volume = 22m3
we will work on the equation directly because they are already in there SI units
density = 42 kg/22m3
density = 1.9090909090909
which if rounded can become 1.9 kg/m3
ans = the object's density is 1.9090909090909 kg/m3 or 1.9 kg/m3
