Answer:
144N
Explanation:
A Body Of Mass 6 Kg Moves In A Straight Line Along Y Axis The Position Time Relation Of Object Is Given As Y =T3-75T, Where Y Is In The Meter And T In Seconds What Is The Force Acting On The Body At Times T=4 Second
Y = T³ - 15T
Y is the position
Velocity = dY/dt
=> Velocity = d(T³ - 15T)/dt
=> Velocity = 3T² - 15
accelearation = dV/dt
=> accelearation = d(3T² - 15)/dt
=> accelearation = 6T
acceleration at T = 4 is 6 * 4 = 24 m/s²
Force = mass * acceleration
=> Force = 6 * 24 = 144N
144N force acting on body
