Force, F = mg sin(theta)
F = 89 x 9.8 x sin(13) = 196.20 N
To going uphill biker must apply twice of above force,
So,
Net force, Fn = 2 x 196.20 = 392.4 N
Comment in case any doubt please rate my answer....

Imagine a cyclist coasting down a 5.0◦ incline at a constant speed of 6.0 km/h because of air resistance. If the total mass of the bicycle + cyclist is 50 kg, how much force must be generated to climb back up the incline at the same speed (and same air resistance)?
A bicyclist coasts down a 6.0 ∘∘ hill at a steady speed of 4.0 m/s . Assuming a total mass of 85 kgkg (bicycle plus rider), what must be the cyclist's power output to climb the same hill at the same speed?
A bicyclist coasts down a 6.5 ∘ hill at a steady speed of 3.5 m/s . Part A Assuming a total mass of 75 kg (bicycle plus rider), what must be the cyclist's power output to climb the same hill at the same speed? Express your answer using two significant figures.
If a bicyclist of mass 69 kg (including the bicycle) can coast down a 7.5 degree hill at a steady speed of 6.0 km/h because of air resistance, how much force must be applied to climb the hill at the same speed (and the same air resistance)? Use two sig figs.
A bicyclist maintains a constant speed of 4.00 m/s up a hill that is inclined at 10.0 degrees with the horizontal. Calculate the work done by the person and the work done by gravity if the bicycle moves a distance of 19.0 m up the hill. The combined mass of the rider and the bike is 88.0 kg. 1) Calculate the work done by gravity. 2) Calculate the work done by the person.
Problem 40 A bicyclist maintains a constant speed of 4.00 m/s up a hill that is inclined at 10.0 with the horizontal. Calculate the work done by the person and the work done by gravity if the bicycle moves a distance of 19.0 m up the hill. The combined mass of the rider and the bike is 86.0 kg. 1) Calculate the work done by gravity. (Express your answer to three significant figures.) kJ Submit You currently have 2 submissions...
Please help a.How high will a 1.60-kg rock go from the point of release if thrown straight up by someone who does 80.0 J of work on it? Neglect air resistance. Express your answer to three significant figures and include the appropriate units. b.A bicyclist coasts down a 9.0 ∘ hill at a steady speed of 6.0 m/s . Part A Assuming a total mass of 95 kg (bicycle plus rider), what must be the cyclist's power output to climb...
3.) A jet plane is flying with a constant speed along a straight line at an angle of 30° above the horizontal. The plane has a weight W of magnitude 86500 N and its engines provide a forward thrust T of magnitude 103000 N. In addition, the lift force L (directed upwards perpendicular to the wings) and the force R of air resistance (directed opposite the motion) act on the plane. Find L and R. [L = 74900 N; R=...
A vehicle of mass 2000 kg has a constant resistance to motion of
3000 N. The maximum speed of the vehicle, when travelling on a
horizontal road, is 120 km/hour. Find the acceleration of the car
when it is travelling at a speed of 50 km/hour up a hill inclined
at an angle of 3o to the horizontal, with the engine
operating at maximum power (assume the resistance to motion
remains unchanged whether the car is travelling uphill or
horizonally...
You are cycling at a constant speed of 10.0 m/s on a level road. (a) If the net resistive force acting against you from things like air resistance is 32.0 N, what is your power output as you pedal? (b) How much additional power is required to maintain this speed up a hill inclined at 3.00° with the horizontal? Assume the combined mass of you and your bicycle is 58.0 kg. If you need a value for the acceleration due...
