an object of mass 50 kg is accelerated from a velocity of 4 metre per second 8 metre per second in 8 second calculate the initial and final momentum of the object and also find the force exerted on the object. |
|
Answer» We are given that Mass of object (m) = 100 kg Initial velocity (u) = 5 m/s Final velocity (ν) = 8 m/s TIME = 6 sec. Initial momentum of the object = mu = 100 x 5 = 500 kg m/s ∴ Final momentum of the object = MV – 100 x 8 = 800 kg m/s ∴ Magnitude of the force exerted on the object (F) = Change in momentum T i m e Change in momentumTime = 800 − 500 6 = -object-of-mass-100-kg-is-accelerated-uniformly-from-a-velocity-of-5-m-s-to-8-m-s-in-6-sHope it helps you keep SMILING :) |

A body completes 2 rounds on a circular track of radius 7m in 10 seconds . calculate: a. distance covered. b. speed (take pie=22/7) |
| Answer» TION:Distance covered by the body = Circumference of the circle.We know circumference of the circle is 2πr We have, r = 7m Taking π = 22/7 Circumference is :- = 2 × 22/7 × 7= 44mSince, It covered 2 ROUNDS Total distance = 44 × 2 = 88 So the body completes 88M in 10sThen, Speed = 88 ÷ 10= 8.8m/s | |
