Question 3 (1d motion, non-constant a) An object is recorded to move under the influence of...
What happens to the motion of an object under the influence of a single constant force as you decrease the object’s mass? A) the magnitude of the acceleration would increase B) the magnitude of the velocity would increase but the acceleration would remain the same C) the magnitude of the acceleration would decrease D) the magnitude of the velocity involved would decrease but the acceleration would remain the same
(ii)(a) An object is moving with constant acceleration in 1D (along a straight line), what is its position x(t) as a function of time, given its initial position xo, initial velocity vo and acceleration a? (b) How do you derive its velocity as a function of time from x(t)? (c) Why is the funciton of x(t) the key for predicting eclipses and hurricanes?

A 2.5-kg object attached to an ideal spring with a force constant (spring constant) of 15 N/m oscillates on a horizontal, frictionless track. At time t = 0.00 s, the cart is released from rest at position x = 8 cm from the equilibrium position. (a) What is the frequency of the oscillations of the object? (b) Determine the maximum speed of the cart. (c) Find the maximum acceleration of the mass (d) How much total energy does this oscillating...
