A cart that can move along a straight track has a mass of 3.00 kg and an initial velocity of 4.00 m/s in the negative x-direction. The cart is then subjected to a net force that is initially in the positivex-direction, but which then eventually switches direction to the negative x-direction, as shown in the graph of force as a function of time below. The force is directed only in the +x or -x direction.F (N)+30-+20-+10-0-Þ1(s)10202530-10--20+(a) Complete the table below to show the cart's momentum and velocity at the indicated times. Use + and - signs, as appropriate.TimeMomentumVelocityt = 0sp =kg • m/sV =m/st = 20 sp =kg • m/sV =m/st = 25 sp =kg • m/sV =m/s(b) The cart's momentum at t = 20 s is exactly the same as its momentum at t =s.

Suppose that Zak's younger cousin, Greta, sees him sliding across the hall and takes off her shoes so that she can slide as well (assume her socks have the coefficient of kinetic friction of 0.250). Instead of getting a running start, she asks Zak to give her a push. So, Zak pushes her with a force of 125 N over a distance of 1.00 m. If her mass is 20.0 kg, what distance d does she slide after Zak's push ends? Remember that the frictional force acts on Greta during Zak's push and while she is sliding after the push.

A wooden ball of weight 196 newtons is dropped vertically from a height of 100 meters above the ground. Throughout the fall, drag is present by a factor 4v due to air resistance, where v is the velocity of the ball at time t (in seconds). After how many seconds will the ball impact the ground?
