In procedure 1: suppose the hanging mass is

mH = 203 g and the mass of the cart is
mC = 1286 g.

a) Assume there is no friction anywhere in the system, and the system starts at rest.

i. Find the magnitude of the acceleration of the masses.
a = m/s2

ii. Find the magnitude of the tension in the string.
T = N

iii. If the track has length L = 2.79 m, find vf, the speed of the cart just before it hits the barrier.
v = m/s

iv. Find tf, the time it takes the cart to travel the 2.79 m to hit the barrier.
tf = s
