Question

A 4.00-kg object has a velocity of 3.00i m/s at one instant. Eight seconds later, its velocity

has increased to (8.00i +10.0j) m/s. Assuming the object was subject to a constant total

force, find (a) the components of the force and (b) its magnitude.​

Answer 2

Explanation:

v=u+at

u=3icap

v=8icap+10jcap

t=8

on solving

a=5/8icap + 10/8jcap

force = m×a

a)force= 5/2icap + 5jcap

b)magnitude = 5√5/2
