When a force acts on a ball of mass 150 g for 0.1 sec, it produces an acceleration of 20 m/s2. What is the value of this impulsive force? |
0.3 N-s 0.5 N-s 0.1 N-s 1.2 N-s |
0.3 N-s |
Impulse : \(I = F \Delta t\) \(F = m * a\) \(F = \frac{150}{1000} \text{ kg} * 20 \text{ m/s^2}\) \(F = 3 \text{ N}\) \(I = 3 \text{ N} * 0.1 \text{ sec}\) \(I = 0.3 \text{ N-s}\) |
