计算一道英文数学题 关于velocity速度的

计算一道英文数学题 关于velocity速度的At a time of t seconds, a particle moves a distance of s meters from its starting point, where s=5 sin(1.7 t)a) Find the average velocity (correct to four decimal places) between t=1 and t=1+h for the following values of h. If h=0.1 then the average velocity over the time period [1,1.1] equal__________________m/s. If h=0.01 then the average velocity over the time period [1,1.01] equals______________m/s. If h=0.001 then the average velocity over the time period [1,1.001] equals___________________m/s. If h=0.0001 then the average velocity over the time period [1,1.0001] equals_____________________m/s. (b) Using the results of part (a), estimate the instantaneous velocity at time t=1.
