Explanation:
In first case, the forces on LHS and on RHS is the same i.e. 3 N. The force acting on the car is balanced force. As a result, the car will not move at all.
In second case,
Force on RHS = 2000 N
Force on LHS = -6000 N
Net force acting on it is given by :
F = 2000+(-6000)
= -4000 N
Hence, this is the required solution.
Answer:
the final angular speed of the wheel at the bottom is 25.5 rad/s
Explanation:
The computation of the final angular speed of the wheel at the bottom is as follows:
As we know that

Hence, the final angular speed of the wheel at the bottom is 25.5 rad/s
We simply applied the above formula so that the final angular speed could come
Hello!
A car travels 35.0 mph north for 1.00 hour, then 40.0 mph east for 0.0500 hour, and finally 50.0 mph northeast for 2.00 hours. Calculate the average speed.
We have the following data:
* velocity (in mph)
(V1) = 35.0 mph
(V2) = 40.0 mph
(V3) = 50.0 mph
* weights for the time (in hours)
(T1) = 1.00 hour
(T2) = 0.0500 hour
(T3) = 2.00 hours
We apply the data to the weighted average formula to find the average speed, let us see:






Answer:
The Average Speed is approximately 44.92 mph
