Question

77. A horizontal force of 150N produces
an acceleration of 2m/s2 in a body placed
on a horizontal surface. A horizontal force
of 200N produces an acceleration of
3m/s2. The mass of the body and coefficient
of kinetic friction are (g = 10ms-2)
1) 50kg, 0.1 2) 25 kg, 0.1
3) 50 kg, 0.5 4) 50 kg, 0.2​

Answer 1

Answer:

mass=50kg and

frictional co-efficient=0.1

Answer 2

Explanation:

N ieqal to mg

fl. ieqal to neu n ieqalto neu mg

-f - FL is equal to Ma

150 - 10 new m is equal to 2m first equation

200 - 10xm is equal to 3 m second equation

50 grams is equal to m X is equal to 0.1
