Aforce of 450 n accelerates a box across a frictionless surface at a rate of 15 m/s 2 . what is the mass of the box?

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
