Question

body of mass is 10kg. A force is applied to it. Show that in 30 seconds it attains a velocity of 40m/s. Calculate the velocity of force applied.​

Answer 1

Explanation:

given,

mass = 10 kg

t = 30 s

v= 40m/s

u = 0 m/s

since, a = v - u / t = 40 /30 = 4/3 m/ s^2 force needed = m* a = 10 * 4/3 = 13.3 N

Answer 2

Answer:

Body of Mass = 10 kg .

In 30 seconds it attains a velocity of 40m/s.

Formula to calculate the velocity of force :

= Area under the graph / mass of object

= velocity - u / t = 40 / 30 = 4 / 3 mm/s ^ 2

= m × a

= 10 × 4/3

= 13.3.

Answer = 13.3 .
