Welcome back maame — missed you this week. Step 1: Identify the given values. The mass of the body m = 2.5 kg. The angle of inclination = 65^. The initial velocity u = 4 m/s. The time t = 2 s. The acceleration due to gravity g = 10 m/s^2. Step 2: Calculate the acceleration of the body down the smooth inclined plane. For a smooth inclined plane, the acceleration a is given by the component of gravity acting along the incline. a = g Substitute the values: a = 10 m/s^2 × (65^) a = 10 m/s^2 × 0.9063 a = 9.063 m/s^2 Step 3: Use the kinematic equation to find the final velocity. The final velocity v can be found using the equation: v = u + at Substitute the initial velocity, acceleration, and time: v = 4 m/s + (9.063 m/s^2 × 2 s) v = 4 m/s + 18.126 m/s v = 22.126 m/s Rounding to one decimal place: v ≈ 22.1 m/s The velocity after 2 seconds is 22.1 m/s.
