The net force is <u>zero</u><u>.</u>
According to Newton's first law, every body continues in its state of rest or in a state of uniform motion in a constant direction, unless acted upon by an external unbalanced force. This law leads to the principle that no force is required to keep the body moving with a constant velocity.
According to Newton's second law, force acting on a body is proportional to the rate of change of momentum produced in the body. In simple terms, the force <em>F</em> acting on a body is given by the product of its mass and the acceleration produced in it. Thus, when a force acts on a body, the body is accelerated.
A body is said to be accelerated, if its speed changes or its direction changes or if both its speed and its direction changes.
Since the car in the question is travelling at a constant speed of 60 mph, it is not accelerated, hence the total external force acting on the car is zero.
Answer:
Centripetal acceleration will be equal to
Explanation:
We have given time taken to cover 180° is 0.5 sec
So time taken by 360° is equal to = 2×0.5 = 1 sec
Radius of the circle r = 0.520 m
So distance
So velocity
We have to find the centripetal acceleration
Centripetal acceleration will be equal to
So centripetal acceleration will be equal to
Answer:
Yes
Explanation:
A body can possess velocity at the same time in horizontal and vertical direction
For example
A projectile
A negative object so it takes in the charged object and nothing will happen until something else would touch it I think
Answer:
ooh thanks but don't give me advise
