Phys201-1 Summer2020 <A HW (Part 1)Phys201 Problem 7.79 A block of mass m = 2.70 kg starts from the rest and slides down a 300 incline which is 3.60 m high. At the bottom, it strikes a block of mass M-7.50 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored Determine the speed of the block with mass m2.70...
4. A small block of mass $m_{1}=4 k g$ is placed at rest on a larger block of mass $m_{2}=6 \mathrm{kg}$. The coefficient of friction between the two block is $\mu=0.3 .$ And the horizontal surface is smooth. A constant force $\mathrm{F}$ is applied on the block.
The situation is given in the figure below.

A Review Part A The 11 lb block is originally at rest on the smooth surface. It is acted upon by a radial force of 2 lb and a horizontal force of 7 lb, always directed at 30 from the tangent to the path as shown. Determine the time required to break the cord, which requires a tension T-30 lb. Neglect the size of the block for the calculation. (Figure 1) Express your answer with the appropriate units.
