Question
Transcribed Image Text:A crate of mass 42.0 kg is being transported on the flatbed of a pickup truck. The coefficient of static friction between the crate and the truck's flatbed is 0.290, and the coefficient of kinetic friction is 0.180.
(a) The truck accelerates forward on level ground. What is the maximum acceleration the truck can have so that the crate does not slide relative to the truck's flatbed? (Give the magnitude of the
acceleration.)
m/s2
(b) The truck barely exceeds this acceleration and then moves with constant acceleration, with the crate sliding along its bed. What is the acceleration of the crate relative to the ground? (Give the
magnitude of the acceleration.)

- If a single constant force acts on an object that moves on a straight line, the objects velocity is a linear function of time. The equation v = vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position? Assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = vi kx, where k is a constant coefficient and x is the position of the object. Find the law describing the total force acting on this object.arrow_forwardA crate of mass 55.6kg is being transported on the flatbed of a pickup truck. The coefficient of static friction between the crate and the trucks flatbed is 0.330, and the coefficient of kinetic friction is 0.320.

What is the acceleration of the crate relative to the ground?arrow_forwardA person pushes horizontally with a force of 200. N on a 56.0 kg crate to move it across a level floor.

The coefficient of kinetic friction between the ramp and thelower box is 0.444, and the coefficient of static friction between the two boxes is 0.800. What is the magnitude of the maximum acceleration the man can pull the boxes up the ramp without having the top box slip off the bottom box?arrow_forwardThe coefficient of static friction between block A and a horizontal floor is 0.470, and the coefficient of static friction between block B and the floor is 0.300. The mass of each block is 2.00 kg, and they are connected together by a cord. What is the tension in the cord connecting blocks A and B just before they start to slide?arrow_forward
- A flatbed truck is carrying a 30-kg crate up a sloping road at a constant speed. The coefficient of static friction between the crate and the bed is 0.60, and the coefficient of kinetic friction is 0.25. What is the maximum angle of the slope that the truck can climb if the crate is to stay in place? Answer in degrees.arrow_forwardTwo workers are sliding 390 kg crate across the floor. One worker pushes forward on the crate with a force of 450 NN while the other pulls in the same direction with a force of 290 NN using a rope connected to the crate. Both forces are horizontal, and the crate slides with a constant speed. What is the crate's coefficient of kinetic friction on the floor?arrow_forwardA boy has stacked two blocks on the floor so that a 5.00kgblock is on top of a1.60kg block. If the coefficient of static friction between the two blocks is 0.400 and the coefficient of static friction between the bottom block and the floor is 0.220,with what minimum force should the boy push horizontallyon the upper block to make both blocks start to slide together along the floor?arrow_forward
- Consider a wooden ramp angled 31.7 degrees above horizontal. If a 20.3-kg wooden block is given a strong shove up the ramp so that it has an initial velocity of 22.9 m/s, how long (in seconds) will it take the block to reach its maximum height (before it starts sliding down)? The coefficient of kinetic friction between the block and the ramp is 0.402.arrow_forwardA crate rests on the flatbed of a truck that is initially traveling at 15 m/s on a level road. The driver applies the brakes and the truck is brought to a halt in a distance of 38 m. If the deceleration of the truck is constant, what is the minimum coefficient of friction between the crate and the truck that is required to keep the crate from sliding?arrow_forwardA block is placed on the midpoint of a ramp that is inclined at an angle of 39.8º from the horizontal, at which point the block immediately starts to slide down the ramp due to the fact that the static friction limit for this particular case is insufficient to hold the block in place. If the coefficient of kinetic friction between the block and the ramp is 0.277 , what is the magnitude of the acceleration of the block as it slides down the ramp.arrow_forward
