a=56/15 * t/10
a= dv/dt
dv= 56/150 t dt
v= INT dv= 28/150 t^2 from zero to 10
vf=2800/150 m/s
An object in space is initially stationary relative to the Earth. Then, a force begins acting on the object, starting with a force of 0 N, and increasing at a uniform rate until the magnitude of the force is 56 N after the force has acted for 10 s. The body has a mass of 15 kg. What is the speed of the object at 10 s?
