Q4. A small block slides up a section of curved slope described by the equation Y = 10(1-e0*) where both x and y are in meters, as shown in Figure. The block has a speed of v = 3.0 m/s as it passes through x = 1.0 m. There is a kinetic friction acts between the block and surface. y (m) y =10 (1 - e**) v = 3.0 m/s g = 9.8 m/s x (m) 1 Figure Q 4 a) Determine the normal component of acceleration of the block at this instant. b) If a = - 10.2 m/s at this point, Determine the coefficient of kinetic friction between the two surfaces.
A sled, of mass 18.6 kg, is stationary when it starts to slide down an icy hill. The hill is 13.0 m tall. Assuming friction is minimal, what is the speed of the sled at the bottom of the hill? Give your answer in m/s to 1 decimal place.
1- A hijacker drops an 80 kg chest of gold from an airplane. Neglecting air resistance, how far does the chest fall in 6 seconds? 2- A 20 kg brick falls freely under gravity from the roof of a tall building. What is the (“final”) speed of the brick after it has fallen 8 meters? (Note: at this point the brick has not yet hit the ground. It is still falling.)
