Bthe accleration of the object is zero Cbody moves with uniform velocity Dall the aboveSubmit Show that area under the velocity-time graph of an object moving with constant acceleration in a straight line in certain time interval is equal to the distance covered by the object in the interval...
An object moves along a straight line so that at any time t its acceleration is given by a(t)=6t. At time t=0, the object's velocity is 10 and the object's position is 7. What is the object's position at time t=2? ( )...

According to these results, an object with greater width or an object in which the part contacting with the interface is divided into shorter portions along the driving direction can have a larger maximum static friction force under a constant loading force. The present results will provide new ...
An object is being acted upon by three forces and moves with a constant velocity. One force is 60 N along the x-axis, the second is 75 N along the y-axis. What is the magnitude of the third force? What happens when your acceleration is in ...
On a horizontal surface, an object of mass 5 kg moves with uniform velocity of 2 m/s when a force of 4 N is applied.What is its acceleration when the force is increased to 12 N?试题答案 在线课程 答案:解析: Frictional force f=4 N Resultant force F=ma-f=12-4=8 N Therefore, ...
An object is traveling at a constant speed of 12.0 m/s when it slows to a stop. If it takes 10.0 m for the object to stop, what is the magnitude of its acceleration? A car starts from rest and reaches a velocity of 8 m/s in 4 sec...
What are the linear speed and the linear acceleration of the moving end of the stick as that end moves through its lowest point? 7.14 A uniform disk of mass 2.5 kg has a radius of 0.50 m. What constant tangential force must be applied to the periphery of the disk if the disk is to...
End (E) Another spatio-temporal position where trajectory ends, with similar definition h point, instant i, where instant = t end; Move (M) Defined by a time interval [t beginMove, t endMove] during which the object is moving. A move is defined by a time varying point ; Stop (S)...
For the ‘Point Load’ model, the load is applied as an external load, without taking into account the interaction with the structure. Consequently, the global mass, damping, and stiffness matrices are time-independent and remain constant throughout the transient analysis. The external force will...
