Along y-axis
a = F/m = 2/1 = 2 m/s^2
Velocity after 4s
v = at
v = 2 × 4
v = 8 m/s
Along x-axis
Velocty after 4s = 8 m/s
Speed after 4s = √(v_x^2 + v_y^2)
= √(8^2 + 8^2)
= 8√2 m/s
a = F/m = 2/1 = 2 m/s^2
Velocity after 4s
v = at
v = 2 × 4
v = 8 m/s
Along x-axis
Velocty after 4s = 8 m/s
Speed after 4s = √(v_x^2 + v_y^2)
= √(8^2 + 8^2)
= 8√2 m/s
