Question

3. Friction with the ground acts to push a car forward when the wheels turn. If one ssurmes the ground is flat, level, and dry and I,-07, (a) what is the maximum acceleration a car can have starting from rest if it is not to skid in the processt(o 60 mph time be for such a car? Figure 2: Two crates in uniform motion 4. Two crates connected by a rope lie on a horizontal surface as shown in the figure. Crate A has mass 3 kg, and crate B has mass 4 kq. The coefficient of kinetic friction between the crates and the surface is Hs 0.25. The crates are pulled to the right at constant velocity by a horizontal force Fp. (a) Calculate the tension, T, in the rope connecting the blocks. (b) Calculate the magnitude of Fp. Questions 3&4 answer all parts of both
