The particle P starts from rest at point A at time t-Oand changes its speed thereafter at a constant rate of 3.0g as it follows the horizontal path shown. Determine the magnitude and direction of its total acceleration (a) just before point B, (b) just after point B, and (c) as it passes point C. State your directions relative to the x-axis shown (CCW positive) and choose the angle with the smallest magnitude. -3.02 m-- 3.63 m Answers: (a) Just before B, a- 29.43 m/s?, e- (b) Just after B, m/s?, e- 57.132 -58.992 (c) Passing C, 144.445 m/s?, e-i -78.25

A block of mass m = 2.00 kg rests on the left edge of a block of larger mass M = 8.00 kg. Thecoefficient of kinetic friction between the two blocks is 0.300, and the surface on which the 8.00-kgblock rests is frictionless. A constant horizontal force of magnitude F = 10.0 N is applied to the2.00-kg block, setting it in motion as shown in Figure P5.65a. If the length L that the leading edgeof the smaller block travels on the larger block is 3.00 m, (a) how long will it take before this blockmakes it to the right side of the 8.00-kg block, as shown in Figure 3? (Note: Both blocks are set inmotion when F is applied.) (b) How far does the 8.00-kg block move in the process?

Think about how this relates to (c). Ihe center of the circle? 2. A 1500 kg car is driving on a concrete highway, on a sunny day. The road makes a sharp turn, with a radius of curvature of 50. meters. What is the maximum speed at which the car can make the turn without sliding sideways?? The centripetal force is provided by the friction force that the concrete road exerts on the rubber tires. Calculate the friction force, then plug that into F.-mv/r, as F M 9 EESE
