The discussion focuses on solving a physics problem involving a 35kg mass subjected to a constant force of 55N, with the goal of determining the time required for the mass's speed to double from an initial velocity of 40m/s. The acceleration is calculated using the formula a = F/m, which results in an acceleration of 1.57 m/s². Participants emphasize the use of SUVAT equations to find the time, specifically highlighting the need to select the appropriate equation based on known variables.
PREREQUISITESStudents studying physics, educators teaching kinematics, and anyone interested in applying Newtonian mechanics to solve real-world problems.
In the usual form, there are five variables and five equations. Each equation involves a different four of the variables. Typically, you know three values and wish to find a fourth. So pick the equation involving those four.Chris18 said:I am to the most of them... Still I don't know which one to use. Could you give me a hand here?
