A block of mass m = 5.8 kg is pulled up a 0 = 25° incline as in Figure P4.24 with a force of magnitude F= 32 N. (a) Find the acceleration of the block if the incline is fric- tionless. (b) Find the accel- eration of the block if the Figure P4.24 coefficient of kinetic friction between the block and incline is 0.10.

A 9.08 kg mass is released from rest while on and incline of 58.65 degrees. If the coefficient of kinetic friction is 0.301, what is the magnitude of the acceleration of the mass?

A warehouse worker pushes a box with a mass of 11.6 kg in a horizontal plane at a constant speed of 3.4 m / s. Calculate the horizontal force that the worker must apply in order to keep this motion, if the kinetic coefficient of friction between the box and the surface is µ = 0.21.

A jet airplane has an instantaneous acceleration of 1.99m /s^2 at an angle of 18.5^oabove the horizontal.Compute the horizontal and vertical components of force exerted on a 55.0kg passenger by the airplane seat?

Suppose that Zak's younger cousin, Greta, sees him sliding across the hall and takes off her shoes so that she can slide as well (assume her socks have the coefficient of kinetic friction of 0.250). Instead of getting a running start, she asks Zak to give her a push. So, Zak pushes her with a force of 125 N over a distance of 1.00 m. If her mass is 20.0 kg, what distance d does she slide after Zak's push ends? Remember that the frictional force acts on Greta during Zak's push and while she is sliding after the push.

A 260-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0 with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.870, and the log has an acceleration of 0.800 m/s2. Find the tension in the rope.

A 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.

The coefficients of friction between a box of mass 9.5 kg and the horizontal floor beneath it are ?? =0.65 ??? ?? = 0.49. The box is stationary. The magnitude of the minimum force that would suffice to setthe box into motion is ? .

A 1.88 kg mass is released from rest while on and incline of 57.18 degrees. If the coefficient of kinetic friction is 0.455, what is the magnitude of the acceleration of the mass
