Question

A ball of mass 2kg travelling in a straight line at 4ms^-1 is acted on by a force of 3N acting in the direction of motion for 5 seconds. What is the speed of the ball after 5 seconds?

vf=vi+at but a=force/mass

a = 3÷2= 1.5

vf=4+1.5×5=

vf=4+7.5

vf=11.5m/s^-1


Is this correct? If not please can you correct it for me
