Given the velocity-time graph of an object.
The slope of a velocity-time graph gives the acceleration acting on the object.
From the graph, we can see that the slope of the graph is zero. That is, the velocity of the object is constant and hence the net acceleration acting on the object is zero.
From Newton's second law, the net force acting on an object is given by the product of the mass of the object and its velocity. Therefore when the acceleration of the object is zero, the net force on the object is also zero.
Therefore the net force acting on the given object is zero. Hence, the correct answer is option A.
Answer:
Explanation:
As the truck is moving towards right and there is no friction between the truck and dog, it experiences a psheudo force, so the dog moves towards left.
Option (D)
Answer:
13 sec
Explanation:
Hello
by definition the acceleration is a vector derived magnitude that indicates the speed variation per unit of time

Let
Vi=4.0 m/s
a=1.0 m/s2
Vf=17.0 m/s
ti= (0)sec
t2= unknown

Answer: 13 sec
I hope it helps
