WebQuestion 1: Calculate the force needed to speed up a car with a rate of 5ms –2, if the mass of the car is 1000 kg. Solution: According to question: Acceleration (a) = 5m/s 2 and Mass (m) = 1000 kg, therefore, Force (F) =? We know that, F = m x a = 1000 kg x 5m/s 2 = 5000 kg m/s 2 Therefore, required Force = 5000 m/s 2 or 5000 N WebForce =ma = 4*0.5 = 2N . 12. Initial velocity (u) = 40km/hr = 11.11m/s.
