A 13 kg zorb is launched downwards with an initial velocity of 1 m/s.   The motion of the zorb is governed by Newton's 2nd law which states that 𝑚 𝑑 𝑣 𝑑 𝑡 = 𝑚 𝑔 − 𝑐 𝑣 2 The manufacturer of the zorb states that if SI units are used then c=3.5 Use Euler's method with a step size of 0.5 seconds to find the velocity of the zorb 1 second after release.  You should use the approximation that g=10 𝑚 / 𝑠 2 and enter your final answer to 2 decimal places (the units will be m/s). Using a table like that shown below is recommended.  You can either fill in the table by hand or use excel to do the calculations. t v v' v(t+h)=v+hv' 0 0.5 1 简答题
