Calculate the time taken for the toy to move 16m?

A child is pulling a toy animal of mass 1.8kg, with constant speed 0.6m/s. She then increases the pulling force by 0.36N. Calculate the time taken for the toy to move 16m, from the instant and the pulling force is increased, given that the resistance to motion remains constant throughout the whole motion.|||speed= distance/time


so


time=distance x speed





u do the math |||Simple





Net force = mass * accelleration





distance = (initial velocity)*(change in time) + (1/2)(accelleration)(change in time)^2
