Question

IV. An object of mass 2kg is sliding with a constant velocity of 4 m/s on a

frictionless horizontal table. The force required to keep the object moving with

the same velocity is
a)32N
b)0N
c)2N
d)8N​

Answer 1

Answer:

b =0

Explanation:

because

when an object has cont. velocity it has acceleration =0

force = mass × accelration

f=2×0

f=0

no force is needed
