instructed thanks! Question 11 (1 point) A tennis ball of mass 56g

Question 11 (1 point) A tennis ball of mass 56g moving at (-1.900x10^1) # m/s is struck by a force (2.3x10^2) a N for a time of (1.560x10*1) milliseconds. Calculate the final velocity of the tennis ball in m/s. You do not need to enter a unit vector or units in your answer. +X Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 AnswerQuestion 12 (1 point) A sprinter runs 100.0 metres in (1.03x10^1) seconds. Assuming she starts at rest, calculate the magnitude of her average acceleration. Give your answer in m/s to 3 significant figures Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answer Question 13 (1 point) You mix (2.000x10^2) cm of liquid 1, with a density of (1.15x10^0) g/cm3, and (1.0x10^2) cm of liquid 2, with a density of (8.600x10^-1) g/cm . Calculate the average density in kg/m to 2 sf. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10
