Please solve this tasks and explain with all details the solution, because I am preparing for the exam and there is a chance that I will have similiar tasks. Thank you in advance

Quiz 3 Energy and Work Unless specified otherwise, assume g = 9.81 mfsz. Problem 1 125 pts! Energy How fast is a 1.5 kg ball traveling when it hits the ground 3.5 meters below its original position, given it starts from rest? Assume zero drag. Problem 2 125 pts! Force and Work A sled and its rider (total mass of 35 kg) are moving on a horizontal surface with an initial speed of 3? this. If a force slows them to a stop at a constant rate of 4 mfsg, answer the following: {a} What magnitude F is required for the force? (5 pts} (b) What distance d do they travel while slowing? Use the concept of work [2|] pts] Problem 3 125 pts! Potential EneEgI A 60 kg skier starts from rest at height H = ID m above the end of a skijump ramp and leaves the ramp at angle 9 = 28. Neglecting the effects of air resistance and assuming the ramp is frictionless, nd the maximum height it of her jump above the end of the ramp. Problem 4 [25 gts! Work Done by External Forces A 52Gkg object slides from rest down a ramp that is 500 III long and 300 In high. The coefficient of kinetic friction between the object and the surface is 0.25. Answer the following: (a) Assuming the gravitational potential energy U of the obj ectEarth system is zero at the bottom of the ramp, what is the value of U just before the slide? (5 pts) (b) How much energy is transferred to thermal energy during the slide'? {15 pts] (c) What is the kinetic energy of the object as it reaches the bottom of the ramp? {5 pts) 300 m 500 in
