You are exiting a highway and need to slow down on the off-ramp in order to make the curve. It is rainy and the coefficient of static friction between your tires and the road is only 0.4. If the radius of the off-ramp curve is 36 m, then to what speed do you need to slow down the car in order to make the curve without sliding? m/s Submit Answer | Tries 0/2 Up Left Right Down A spinning disk is rotating at a rate of 5 rad/s in the negative clock-wise direction. If the disk is subjected to an angular acceleration in the counterclock-wise direction at a rate of 2 rad/s2, Find the wheel's angular velocity in rad/s after 2 s. O 9 rad/s. O -4 rad/s. O -9 rad/s. O -1 rad/s. O 1 rad/s. Submit Answer Tries 0/3R M M M #1 #2 An object consistes of balls and rigid (massless) rods as shown above. The distance between axis 1 and axis 2 is 0.4 m.

What is the speed of the water in the second part of the pipe in m/s? m/s Submit Answer Tries 0/2 How much is the pressure change in KPa as the pipe contracts? The density of water is 1000 kg/m3. Enter a positive value for an increase in pressure, a negative value for a decrease. |kPa Submit Answer Tries 0/2 An Arrow (1 kg) travels with velocity 30 m/s to the right when it pierces an apple (2 kg) which is initially at rest. After the collision, the arrow and the apple are stuck together. Assume that no external forces are present and therefore the momentum for the system is conserved. What is the final velocity (in m/s) of apple and arrow after the collision? m/s Submit Answer | Tries 0/2 What is the initial kinetic energy of the apple and arrow system?
