I am totally stuck on these two and I would like to know how to do this problem:(adsbygoogle = window.adsbygoogle || []).push({});

1. A 100 pound weight is resting on a 30 degree ramp with a coefficient of friction µ = 0.35 and is restrained by a rope. What is the tension force of the rope?

Sin 30 degrees = 0.5

Cos 30 degrees = 0.866

Tan 30 degrees = 0.577

2. A jet plane is climbing at a constant airspeed in no-wind conditions. The plane takes off from sea level. The plane is directly over a point on the ground that is 4 statute miles (21,120 ft) from the takeoff point and the altimeter reads 15,840 ft. Find the tangent of the climb angle and the distance that it has flown through the air.

Thanks :)
