Hello I need some help with these 4 questions quickly! Include units and direction if required. Show all work for part marks. Round your final answers to the correct number of significant figures. If you could help me out and put all the questions on a separate sheet of paper showing all solutions to it that would be great! 1-Sheila has just arrived at the airport and is dragging her suitcase to the luggage check-in desk. She pulls on the strap with a force of 199.0 N at an angle of 34.5 above the horizontal to displace it 42.5 m to the desk. Determine the work done by Sheila on the suitcase. 2- A 1.255 kg toy car with a Velcro bumper collides with a 2.445 kg toy truck which also has a Velcro bumper. If the car is traveling at 2.772 m/s and the toy truck was stationary, what is the final velocity of the two toys combined? 3-The top of the Horseshoe Falls at Niagara Falls is about 57.40 m above the lower river surface. What is the gravitational potential energy of a man in a barrel at the top of the falls if their combined mass is 105.3 kg? 4-A spring with a spring constant of 626.8 N/m is used on a scale for weighing fish. What is the mass of a fish that would stretch the spring by 7.225 cm from its normal length
