Question

Please help. Not my strongest subject

Answer 1

a) You'll notice from "c)" that the distance the object travelled was 75m, so you get
`V_a_v_e_r_a_g_e = 75m/15s = 5 m/s`.

b)
`a = dV/dT`, so
`a = (0-10)/15` and then you get
`a = -2/3 m/s ^(2)`.

c)
`S = S_0 + V_0T + 0,5aT^2` and you get
`S = 10T - (2/6)T^2` and you plug in
`T = 15s` and you'll get
`S = 75m`
