The net external force on a golf cart is 411 N north of tha cart has a total mass of 281 kg what is tha cart acceleration
1 answer:
1.46m/s²
Explanation:
Given parameters:
Mass of cart = 281kg
Net external force = 411N
Unknown:
Acceleration of the cart = ?
Solution:
According to newton's second law " the net force on a car is the product of its mass and acceleration";
Force = mass x acceleration
Since acceleration of the cart is unknown;
Acceleration = =
Acceleration = 1.46m/s²

There are already 2 givens, hence we can do direct substitution to get the answer. To make the process simpler, derive the distance formula from the Work formula.
Work = Force x Distance
Distance =
Work is 450J while the force is 150N hot tub
To get the proper units, get the equivalent of Joule to eliminate newton. A joule Is equal to 1 N-m
Distance =
Distance = 3m
Hence, the hot tub is lifted 3 meters.

Answer:
work done in the process is 0 J.
Explanation:
Given :
Initial pressure of system ,
Final pressure of system ,
Volume of system ,
We know, In thermodynamics work done is defined as :
Here , P is pressure and is change in volume.
Now, coming back to question , it state that the process is isochoric .
Therefore, change in volume ,
Putting value of in above equation we get ,
W = 0 J.
Therefore , work done in this process is 0 J.
Hence, this is the required solution.
