If an object is accelerated from rest to 4 meters per second by 30 N force acting on it over a distance of 6 meters what is the mass of the object?
22.5 kg
The work-energy theorem states:
Net work = change in kinetic energy
force x distance moved along the direction of the force= change in kinetic energy
Wnet = KEf - KEi = DKE.
Work= (30N)x(6m)x (cos0)=180J
final kinetic energy= 0.5(mass)(velocity^2)= 0.5x(4^2)x m
The initial kinetic energy is 0 (because the object is initially at rest, that is with zero velocity)
--> 180= 8m -0
m (mass)= 22.5 kg
What else can I help you with?
How much work would you do if you applied a 200 Newtons to an object and moved it 0 meters?
If an object does not move, no work is performed. Work is performed by a force acting through a distance.
Accelerated motion is repersented by a what line on a distance time graph?
Accelerated motion is represented by a curved line on a distance-time graph. This curvature indicates that the distance covered changes at a varying rate over time, reflecting the object's acceleration. If the object is accelerating uniformly, the curve will be a parabola. In contrast, a straight line indicates constant velocity, where the distance changes at a steady rate.
What is the relationship between rolled distance and time taken?
If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.
How far would an object travel in 30 seconds if its average speed was 31 meters?
If an object travels at an average speed of 31 meters per second, you can calculate the distance it would cover in 30 seconds using the formula: distance = speed × time. Thus, distance = 31 meters/second × 30 seconds = 930 meters. Therefore, the object would travel 930 meters in 30 seconds.
What is the distance traveled by an object that moves with an averace speed of 10 meters and 5 seconds?
Just divide the distance by the time. (In this case, the speed in the answer will be in meters per second.)
What type of motion is a net force acting on an object?
Accelerated motion (F=ma)
How much work would you do if you applied a 200 Newtons to an object and moved it 0 meters?
If an object does not move, no work is performed. Work is performed by a force acting through a distance.
How do you interpret how an object is moving from a distance time graph?
If the distance is not changing, the object is not moving. If the distance is increasing or decreasing linearly then the object is moving at a constant velocity. If the distance is increasing or decreasing parabolically then the object is being accelerated or decellerated.
What does the speed of an object depend on?
The speed of an object depends on many things, such as the force that accelerated it, the forces now acting on it, and the object's current speed and mass themselves.
What objects have accelerated motion?
Any object on which an unbalance force is acting will accelerate - i.e., its velocity will change.
When the net forces acting on an object sum to zero then the object is acceleration?
When the net forces acting on an object sum to zero then the object's acceleration is zero.
What object do you measure in meters?
Length or distance is measured in meters.
How do you calculate the net torque acting on an object?
To calculate the net torque acting on an object, you multiply the force applied to the object by the distance from the point of rotation. The formula is: Net Torque Force x Distance.
When a mechanic increases the force acting on an object what happens to the distance the object moves?
When the Force increases on an Object, the Distance it travels INCREASES, as does its Velocity.
Problem with solution in uniformly accelerated motion?
what velocity is a taint by an object that is accelerated at .3om/s for the distance of 54m if its initial velocity is 50m/s
How can an object be accelerated when it encounters a force?
I am not sure what you mean, but that's how our Universe works. If there is a net force acting on an object, its velocity will change - in other words, it will accelerate.
What two thing does acceleration depend upon?
Acceleration depends on the mass of the object being accelerated and the net force acting on the object.
