Question

A skier wants to build a rope tow to pull herself up a ski hill that is inclined at 15 with the horizontal. Calculate the tension needed in the rope to give the skier's 54kg body a 1.2 m/s^2 acceleration.

Answer 1

Choose from the options below:( to get you thinking)
A 202 N

B 222 N

C 242 N

D 262 N

Answer 2

I tried solving but my answer is so different from the choices above. I wanna know how to solve it.

Answer 3

who says cylinder's choices are correct?
How did you attempt to solve the problem?

Answer 4

assuming no friction, the downward acceration due to gravity along the slope is g*sin15.
tension=mmass(acceleration+g*sin15)=
= 54(9.8*sin15+1.2)

Answer 5

54(9.8*sin15+1.2) will show you the option it is

Answer 6

and one of the options is right so do that working out to find out which one

Answer 7

Thanks I already figured out how to solve it.
