An object travels a given distance at a speed of 5 m/s. if the object travels the same distance at a higher speed, how will the faster speed affect the time it takes the object to travel the distance? a. it will take less time to travel the distance. b. it will take more time to travel the distance. c. the time will remain constant. d. the time will not be affected.

Modify the equation fδt=δ (mv) to find the force of friction.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?
