Question

A person with mass m is skateboarding across level ground on earth with a speed vo when they
come to a small slope that raises them a distance h higher than ground level over a distance d, as
shown in the figure below. A frictional force with magnitude F, is also acting on the skateboard
opposing the direction of motion as it travels up the slope.
i
●)
d →
i
●)
●)
a) Derive an expression using the defined variables (and g) for the speed of the person after
they reach the top of the slope.
b) If the person's mass m = 50 kg, their initial speed is vo = 3 m/s, the slope raises them
h = 0.4 m over a distance of d = 2 m and the magnitude of the force of friction is
F, = 2 N, what is their speed at the top of the slope?

You have put a sonar device at the top of a frictionless inclined plane, as shown in the diagram below. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. 0 For an angle below the horizontal of 6.46, we see that our object has slid a distance 1.13 m, as measured along the incline itself. Calculate the height change in meters - and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o 10% O i 26 QUATU 99+ hp X 55 83°F 3:11 PM 10/16/2022 Ctrl 0
