Web9. Mass (m) = 200g = 200/1000 kg=0.2 kg Force = 10N We have, F = ma ∴ a = F m = 10/0.2 = 50 m/s 2 ∴ Acceleration (a) = 50m/s 2 10. Mass (m) = 20kg Initial velocity (u) = 10m/s … Weba = (30/10) m/s2. acceleration, a = 3 m/s2. By putting m = 1500 kg and a = 3 m/s2 in formula. F = m × a. F = 1500 × 3 N. = 4500 N. Thus the force required in this case is of 4500 newtons. A. Explanation: First let’s …

WebForce is an external agent that changes or tends to change the state of the body. Amount of matter contained in the body is called mass. Inertia: It is the tendency of a body to maintain its state of rest or a uniform motion unless it is acted upon by some external force. It only depends on mass. i.e. Larger the mass large will be the inertia. WebWork and Energy – Numerical Problems. 6.1. A man has pulled a cart through 35 m applying a force of 300 N.
