A contestant in a winter games event pushes a 35.0 kg block of ice across a frozen lake as shown in the figure below. G) The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03. (For each answer, enter a number.) (a) Calculate the minimum force F (in N) he must exert to get the block moving. :qu (b) What is its acceleration (in m/sz) once it starts to move, if that force is maintained? E m/sz 5.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The terminal velocity of a person falling in air depends upon the weight and the area of the person facing the uid. Find the terminal velocity (in meters per second and kilometers per hour) of a 75.5 kg skydiver falling in a pike (headfirst) position with a surface area of 0.145 m2. (Assume that the density of air is 1.21 kg/m3 and the drag coefcient of a skydiver in a pike position is 0.7. For each answer, enter a number.) terminal velocity in m/s E m terminal velocity in km/h E m
