A 3-kg toy car sits at the highest point of a 13-meter-high hill. The car begins to roll down the slope from rest. Assuming the car coasts freely, without any friction or air resistance, what is the car's speed at each of the indicated points? Use for the acceleration due to gravity, g - 9.80 m/s* Note: the diagram below is NOT to scale. Car's speed Car's speed Number Number m/s m/s 13 m r's speed Number 2 m 6...

A 3-kg toy car with a speed of 6 m/s collides head-on with a 2-kg car traveling in the opposite direction with a speed of 4 m/s. If the cars are locked together after the collision with a speed of 3.435 m/s, how much kinetic energy is lost?

The 1800-kg car descends a hill of angle 0 3°. The drag force due to air resistance is k 0.45 kg/m D kv2 for Use the sketch to complete a free-body diagram. From an initial velocity of 29 m/s (65 mph), the car coasts 1600 m along the slope. Determine the velocity at that point Hint: After finding the acceleration, choose a dr vs dvs to integrate the kinematics; the resulting integral simplifies with the substitution, u = denominator, which...

A car of mass 500. kg on a roller coaster ride is raised from
the ground (horizontal dotted line) to point A as shown in the
diagram above. When the car passes point A, its speed is 5.0 m/s,
and then it rolls freely through the rest of the ride with
negligible friction, passing points B, C, D and E. Note that point
D is the highest portion of a circular loop, and point E is the
lowest portion of...
