99.0km/h =27.5m/s (this is the initial speed) The final speed is zero The distance is 50.0m Therefore you use the formula: vfinal²=vinitial²+2ad a=(vfinal²-vinitial²)/2d = (0²-27.5²)/(2x50.0) =-7.5625 or in correct sigdigs -7.56m/s² Hope this helps!
I think its D. because Tea during a cold workout isnt safe at all. Drinking tea while working out adds weight and you just simply dont need tea when working out.. Hope this helps man :)
