Q7. (A=3) A rope at angle of 18.5 above the horizontal provides a tension force of 11.8 N to pull a toboggan along a smooth, horizontal surface. The rope does 214 J of work. Calculate how far the toboggan moves. Q8. (T= 3, A= 2) A block of 1.0 kg with speed 1.0m/s hits a spring placed horizontally, as shown in Figure 7. The spring constant is 1000.0 N/m. Figure 7 (a) Calculate the maximum compression of the spring. (b) How far will the block travel before coming to rest? Assume that the surfaces are frictionless. (a) (b) Q9. (T=2, C=2) A mass -spring system undergoes SHM. The elastic potential energy at maximum stretch is 7.50J, the mass is 0.20 kg, and the spring constant is 240 N/m. Calculate the frequency and amplitude of oscillation Q10 (K=3, C=1) Could an elephant walking slowly across a field have more kinetic energy than a cheetah chasing its prey? Explain your
