tobonga or. 2. A1600 kg car is traveling with a speed of 15.0 m/s. What is the magnitude of the horizontal net force that is required to bring the car to a halt in a distance of 50 m? Ignore air resistance.

A 3 kg particle moves along an x axis, being propelled by a variable force directed along that axis. Its position is given by x = 2 m + (2 m/s)t + ct2 - (3 m/s³)t³ with x in meters and t in seconds.The factor c is a constant. At t = 4 s the force on the particle has a magnitude of 33N and is in the negative direction of the axis. What is c? Number Units

The figure shows three blocks attached by cords that loop over frictionless pulleys. Block B lies on a frictionless table; the masses are mA blocks are released, what is the tension in the cord at the right? 6.70 kg, mB 6.20 kg, and mc = 12.0 kg. When the B C Number Units

SA3. A block is given an initial velocity of 5.00 m/s up a frictionless 20.0° incline. How far up the incline does the block slide before coming to rest? SA4. A man is pulling a crate along a concrete floor. This time, let's be specific. The crate has a mass of 100 kg and the man pulls with a force of 1 250 N. The coefficient of friction between the crate and the floor is 0.2. What is the acceleration of the crate? SA5. A horizontal force of 80 N is used to pull a 20 N wooden box moving toward the right along a horizontal, wood surface as shown. Calculate the magnitude of the frictional force acting on the box. Determine the magnitude of the force acting on the box. Determine the mass of the box. Calculate the magnitude of the acceleration of the box.
