Question

An object of mass 200kg is accelerated uniform from a velocity of 5ms^-1 to 15ms^-1 in 5 sec . calculate the change in the momentum of the object and also find the force acting on it​

Answer 1

Answer:

50 N

Explanation:

please refer to the attachment

Answer 2

Answer:

initial p=mu

p(initial)=200*5

"    "     "=1000kg m/s

p(final)=200*15

"   "     '=3000kg m/s

change in p =3000-1000/5

"   "           '  =400kg m/s
