Answer:
2. A. using the formula: S= ut + (1/2)at^2
B. S= 0(10)+(1/2)(8)(10)^2
S= 400 meters
3. A. 20km/h=20,000 m/36,000s=5.56m/s
S=5.56(10)+(1/2)(8)(10)^2
S= 228.8 meters
B. V= 5.56+(8)(10)
V=85.56 m/s
4. A. A=(20-5)/10
A = 1.5 m/s^2
B. S= 5(10)+(1/2)(1.5)(10)^2
S=125 meters
5. A . using the formula V^2= u^2+2as
0^2=30^2+2a(90)
a=-15m/s^2
B.using the formula V= u+at
0=30-15t
t=2 seconds
