Question

If an object of mass 10 kg is travelling as per velocity-time graph given. Find Force acting on it.​

Answer 1

Explanation:

With your mouth closed, push your lower jaw out and lift your lower lip. You should feel a stretch build just under the chin and in the jawline. Hold the position for 10–15 seconds, then relax.

Answer 2

Answer:

Force of 20N is acting on it in the opposite direction of its motion.

Explanation:

From the graph, v=0 m/s , u=20 m/s, t=10s

a=(v-u)/t = (0-20)/10 = -20/10 = -2 m/s²

acceleration= -2m/s²

(Or retardation = 2 m/s²)

Force = Mass x Acceleration

= 10kg x -2 m/s²

= -20 N
