4. A 0.030 kg toy car is pushed back against a spring-based launcher as shown in Diagram 1. Diagram 1 mmmmm K 0.090 m Diagram 2 shows a graph of the force required to compress the spring 0.090 m. Diagram 2 F (N) d (m) (3 marks) a) What is the work done in compressing the spring? CS Scanned with CamScannerb) Assuming no losses due to heat, what maximum speed is reached by the toy car when it is (3 marks) released? c) If in fact the maximum kinetic energy of the car is 0.18 J, what is the efficiency of the spring-based launcher? (1 mark) CS Scanned with CamScanner6. A space shuttle is placed in a circular orbit at an altitude of 3.00 x 10' m above Earth's surface. a) What is the shuttle's orbital speed? (5 marks) CS Scanned with CamScannerb) The space shuttle is then moved to a higher orbit in order to capture a satellite. Original orbit The shuttle's speed in this new higher orbit will have to be [:I greater than in the lower orbit. E] less than in the lower orbit. ' [j the same as in the lower orbit. 9 (Check one response.) _ (1 mark) c) Using principles of physics, explain your answer to b). (3 marks) Scanned with CamScanner
