Ahorse is harnessed to a sled having a mass of 236 kg, includ- ing supplies. the horse must exert a force exceeding 1240 n at an angle of 35.0° in order to get the sled moving. treat the sled as a point particle.
(a) calculate the normal force on the sled when the magnitude of the applied force is 1240 n.
(b) find the coefficient of static friction between the sled and the ground beneath it.
(c) find the static friction force when the horse is exerting a force of 6.20 x 10^2 n on the sled at the same angle.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
