Answer:
Work done on the car will be 548440.9463 J
Explanation:
We have given mass of the car m = 1075 kg
As the car finally stops so final velocity of the car
Initial velocity of car u = 115 km/hr
Work done is equal to change in kinetic energy
So work done
=
As the work done is negative so work is done on the car to stop it .
Explanation:
The concentration of salt after t minutes is given by :
A tank contains 9000 L of pure water. Brine that contains 40 g of salt per liter of water is pumped into the tank at a rate of 25 L/min.
We need to find the concentration approach at
So,
Put
Since,
C(t) = 40 g/L
So, at the concentration approaches to 40 g/L. Hence, this is the required solution.
Answer:
a.
b.30.4 N
Explanation:
We are given that
Mass of block=m=1.1 kg
Mass of cart=M=3.4 kg
Total mass=m+M=1.1+3.4=4.5 Kg
1.We have to find the maximum acceleration such that block does not slide on the cart.
Normal force=
Substitute the values
Using
Hence, the maximum acceleration such that block does not slide on the cart=
b.
Using the formula
Hence, the magnitude of the force on the cart required to provide the maximum acceleration=30.4 N
