(а). A driver оf а 1200 kg cаr accelerates frоm 13.0 m/s tо 90.0 km/h in 15.0 s. What is the force of the car? (4.0 points) (b). A 1.10 kg falcon catches an absent minded 0.160 kg dove from behind in midair. What is their velocity after impact if the falcon's velocity is initially 20.0 m/s and the dove's velocity is 8.00 m/s? (2.5 points) (c). A 50.0 g object is thrown vertically up at a speed of 30 m/s. How far from the thrown position will the object go up before falling back down to the original location (ignore air friction)? (1.5 points)
