Question

A 10 kg mass is resting on a horizontal surface and force of 80N is applied if u =0.2 the ratio of acceleration without and with friction is
$\frac{4}{ p} \: then \: p = \: \: \: \: {{g \: = 10ms }^{ - 2}}$
​

Answer 1

Answer:

80-umg=ma

80-20=10*a

a=6

this is with friction

now, for without friction

80=10*A

A=8

........ 8/6=4/P

p=3
