Answer:
Fc=5253
N
Explanation:
Answer:
Fc=5253
N
Explanation:
sequel to the question given, this question would have taken precedence:
"The 86.0 kg pilot does not want the centripetal acceleration to exceed 6.23 times free-fall acceleration. a) Find the minimum radius of the plane’s path. Answer in units of m."
so we derive centripetal acceleration first
ac (centripetal acceleration) = v^2/r
make r the subject of the equation
r= v^2/ac
  ac is 6.23*g which is 9.81
 v is 101m/s 
substituing the parameters into the equation, to get the radius
(101^2)/(6.23*9.81) = 167m
Now for part
( b) there are two forces namely, the centripetal and the weight of the pilot, but the seat is exerting the same force back due to newtons third law.
he net force that maintains circular motion exerted on the pilot by the seat belts, the friction against the seat, and so forth is the centripetal force.
Fc (Centripetal Force) = m*v^2/r  
So (86kg* 101^2)/(167) = 
Fc=5253

Answer:
Highest point reached  = 3.37 m
Explanation:
Initial velocity, = 7.1 m/s
Initial vertical velocity = 7.1 sin 61 = 6.21 m/s
Consider the vertical motion of skateboarder,
We have equation of motion, v² = u² + 2as
           Initial velocity, u = 6.21 m/s
           Acceleration, a = -9.81 m/s²
           Final velocity, v = 0 m/s
          Substituting
                        v² = u² + 2as
                        0² = 6.21² + 2 x -9.81 x s
                        s = 1.97 m
So from ramp the position it goes up by 1.97 m
        Highest point reached = 1.97 + 1.4 = 3.37 m
