Answer:
Explanation:
a ) maximum friction possible
= .3 x 30 x 9.8
= 88.2 N
It is friction force which creates acceleration in 30 kg packing case.
Friction force F
F = ma
= 30 x 2.51
= 75.3 N
It will be in north direction , the direction of acceleration.
b ) F = ma
= 30 x 3.63
= 108.9 N
But maximum friction force is 75.3 N , so load will start slipping northward. so friction force will be acting southward.
Friction force = .2 x 30 x 9.8 ( coefficient of kinetic friction applies )
= 58.8 N
towards south .
D. since the star would be larger than the sun, having more mass, its gravitational pull would be stronger thus pulling the planets into it. hope that helped!
You would benefit from your own handled problem because you solved a problem you had.
i’m pretty sure that’s it, going off the info i had.
