Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

two masses are connected by a light string that passing over a frictionless pulley. Mass m1 =3.34kg is on a 50.0-degree incline, and mass m2 =14.2 kg is hanging on the string. the system starts from rest. If the coefficient of the friction between m1 and the incline is 0.878, find the acceleration of the system, in m/s^2.

A train locomotive pulls a train with a mass of 1.10 ✕ 10^7kg on level rails. The locomotive exerts a constant force of 6.90 ✕ 10^5N on the train. How much time does it take to increase the speed of the train from rest to 64.0 km/h? (Ignore any resistance force from the rails on the wheels of the train. Enter your answer in minutes.)

i never practiced a problem like this in chapter six and need some help working through it as i’m rusty on the concepts of 6

A 20kg block is placed on a 30 degree ramp and an acceleration of 4.91m/s^2 is predicted if friction between the block and ramp is ignored. The actual measured acceleration is 3.49m/s^2. Find the Coefficient of friction between the block and the ramp.

A cord passing over a pulley connects two masses, as shown, where m, = 3.60 kg and m, = 7.10 kg. The system accelerates with a magnitude of 1.34 m/s?. The coefficient of kinetic friction between the masses and the incline is the same for both masses. Assume the pulley is frictionless, and the cord is massless. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) m2 m, 35.0° 35.0° (a) What is the coefficient of kinetic friction? (b) What is the tension (in N) in the cord?

Q 5)A force vector F =3i + 3j N is applied on 5 kg mass of body on nonfrictionless horizontal surface. The velocity function of body is v = t + 2 . find the following : 1) frictional force (fs ) 2) the coefficient of friction of surface (μ) . (answer fs =1.7 N , u =0.34)

A monkey pushes a box of mass 25 kg in a straight line across a rough floor. The applied force F has magnitude 85 N and acts downward at an angle 0 = 10° with respect to the horizontal, as shown below. The box is initially at rest at the position x/ a). Find the coefficient of friction between the box and the floor. and it has speed v2 = 0.55 m/s at position x2 = 3.50 m. 0 m, b). What is the net work done? c). How much work (magnitude and sign) is done by the friction force? m Hint: this q involves constant acceleration, Newton's laws, work

A boat and its passengers have a combined mass of 5.10x10^2 kg. The boat is coasting into a pier at a speed of 1.00 m/s. How great a force is required to bring the boat to rest in 1.00x10^2 s?
