Calculate the final speed of an object if its initial speed is 10 m / s. The object has a mass of 5 kg. Initially, it has a height of 20 meters, and it goes down to a height of 15 m. There are no dissipative forces on the object.

Learning Goal To understand how the trajectory of an object depends on its initial velocity, and to understand how air resistance affects the trajectory. For this problem, use the PhET simulation Projectiie Motion.

Question 9 You should be able to answer this question after studying Unit 8. An object moves along a straight line, and its speed v (in metres per second) when at a position r (in metres) from its starting point can be modelled by the differential equation 10 marks 0 dr0, 20), where k is a positive constant (a) Find the general solution of this differential equation in explicit form (b) The speed of the object at its starting point...

Police Report: There were two individuals involved in the accident. No other passengers were present and no other vehicles were involved. There was a truck of mass 1,936 kg traveling Southbound on H and a compact car of mass 1,077 kg travelling Northbound on HWY 26. A bystander claims to have watched the vehicles collide and slide Southbound off the road into a tall grassy ditch. The grass was determined to have a coeficient of friction of 0.6, while the...
