I found my notes!!!
Q1:  A=(triangle)v/t   A=? V=200 t=4  so A=200/4 A=50 m/s^2
Q2: use F=ma get m by it's self so divide a F/a=m F=400 a=25 m=400/25 m=16kg
Q3: use F=ma get a by its self so divide m both side F/m=a F=200 m=40 a=200/40 a=5m/s^2
Q4: use F=ma F=? m=1000 a=20 F=1000(20) F=20000
Hope this helps good luck if any questions just ask me not 100% sure on the first one thou. Please any questions just ask i like this stuff. i can send you my notes if you want?
