Question

Physics numericals for force and laws of motion

Answer 1

Answer:

Question 1: Calculate the force needed to speed up a car with a rate of 5ms–2, if the mass of the car is 1000 kg. Solution: According to question: Acceleration (a) =5m/s2 = 5 m / s 2 and Mass (m) = 1000 kg, therefore, Force (F) =?

Answer 2

Explanation:

Q. A force of 72 dyne is inclined to the horizontal at angle of 60 degree find the acceleration in a mass of 9 gram which move in horizontal direction ?

Q. A force act for 10 seconds on a body of mass 10 kg after which the ceases and the body describe 50 metre in the next 5 second find magnitude of force ?
