3) A constant pulling force of 150 N applied at an angle of 21.7° above the horizontal, accelerates a crate across a rough horizontal surface. The has mass 35.2 kg, and the acceleration is 0.571 m/s. a) What is the normal force acting on the crate? b) What is the friction force acting on the crate? c) What is the coefficient of kinetic friction between surface?
A father pulls a sled and child with a force of 220 N by a rope making an angle of 20 degree with the horizontal. If the sled and child has a mass of 47 kg, to the nearest hundredth of 3 m s what is the acceleration of the sled and child? Two crates of mass 75 kg and 110 kg arc in contact and rest on a rough horizontal surface. A 620 N force is exerted on the...
box. Mary applies a force of 72 N to push a box with an acceleration of 0.46 m/s?. When she increases the pushing force to 79 N, the box's acceleration changes to 0.64 m/s2. There is a constant friction force present between the floor and the (a) What is the mass of the box in kilograms? kg (b) What is the coefficient of kinetic friction between the floor and the box?

Sample Class Problems-Force and Acceleration Prob#l: Two people are pushing a stalled car (the mass of the car is 1850kg). One person applies a force to the car, while the other applies a force of 395N. Both forces act in the same of 560N also acts on the car, but in a direction opposite force arises because of friction and the extent to which the pavement opposes Find the acceleration of the car. direction. A third force to that in...
