Q. An empty sled of mass 25kg slides down a muddy hill with a constant speed of 2.4 m/s. the slope of the hill is inclined at an angle of 15 degrees with the horizontal. calculate the time it takes the sled to go 21m down the slope.
Q. A 1700 kg car traveling at a speed of 23 m/s skids to a halt on wet concrete where f_k 0.50. How long are the skid marks?
A hawk flies in a horizontal arc of radius 12 m at a speed of 4 m/s, and increases its speed at the rate of 1.20 m/s2. Find the acceleration (and direction) under these conditions.
