3F. A 100-N block on a rough 30°-incline is acted upon by a force P as shown causing it to accelerate at 2 m/s down the plane. The coefficient of kinetic friction is 0.30. (a) Draw the FBD of the block (b) Find the magnitude of P. P

For a short period of time, the frictional driving force acting on the wheels of the 2.3-Mg van is FD = (600+2) N, where t is in seconds. (Figure 1) Figure FD 1 of 1 Part A If the van has a speed of 22 km/h when t= 0, determine its speed when t = 5 s. Express your answer to three significant figures and include the appropriate units.

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 block moves on an inclined surface with an initial speed of 1.6 m/s. After sliding down the incline of distance of L=2 m, the speed of the block is 2.2 m/s. the coefficient of friction between the block and the surface is 0.34. find the angle of the incline
