A football player catches a pass and runs down the sideline at vp = 6.0 m/s.  A defending player directly across on the other sideline runs to intercept. If the defending player runs at vd = 9.0 m/s in a straight line, at what angle relative to the sideline should they run to intercept the player? Quiz Kinematics in Two Dimensions Problem 2.png

A boat crosses a 150 m wide river flowing at 8.0 m/s to reach a dock directly on the other side.  If the boat motor can propel the boat at 10.0 m/s across the water, how long (in seconds) will it take the boat to reach the dock assuming it travels in a straight line)?

A 5.00 gram bullet fired from a rifle of barrel length 0.650 m leaves the barrel with a speed of 325 m/s.  Assuming constant acceleration down the barrel, what was the force  acting on the bullet?

Prob 9 pic.png A person is suspended by a rope as shown.  If the person is simply hanging from the rope (acceleration = 0 m/s2), determine the tension in the rope if the mass of the person is 95 kg.

prob 12 pic.png An object slides down a frictionless incline as shown.  Determine the acceleration in (m/s2) for θ = 350.

prob 22 pic.png Determine the magnitude of the acceleration  for m = 2.0 kg, F1 = 4.0 N, F2 = 5.0 N, F3 = 3.0 N, θ1 = 35.00, and θ2 =20.00.

prob 20 pic.png An object of mass m = 80 kg is pulled over a frictionless surface by two horizontal forces as shown.  Determine the direction of the acceleration counter-clockwise relative to the forward direction  for F1 = 175 N, F2 = 130 N, q1 = 200, and q2 = 350.

p7.png Two objects are connected by a rope over a massless, frictionless, pulley. The coefficient of kinetic friction  the surface and m2 is μ = 2.5  Assume m2 slides up the ramp, and determine the acceleration of the masses for m1 = 40.0 kg, m2 = 10.0 kg, and θ= 30.00

A mass m1 = 5.0 kg collides with a mass m2.  The mass m2 accelerates at 4.0 m/s2 and m1 decelerates at 6.0  m/s2.  What is the mass of  m2?

p13.png The coefficient of kinetic friction between the surface and m2 is μ = 0.30.  Determine the acceleration of the masses for m1 = 15.0 kg and m2 = 10.0 kg.
