Two blocks of m1 and m2 are connected by a string and placedon a flat surface. They are initially at rest. The frictioncoefficient μ= 0.2. A force F is exerted on second block. m1= 1 kg F is either 50 N, 20 N, or 4 N m2 = 1.5 kg t1= 4 s t2 = 7 s a) What is the velocity of the blocks at time t1? b) What is the tension of the string T? c) What is the momenta and kinetic energies of the blocks attime t2?

m1= 1 kg F is either 50 N, 20 N, or 4 N
m2 = 1.5 kg
t1= 4 s
t2 = 7 s
a) What is the velocity of the blocks at time t1?
b) What is the tension of the string T?
c) What is the momenta and kinetic energies of the blocks attime t2?
