What is the velocity of the 1.00 kg ball after the collision? O -0.7 m/s O + 2.2 m/s O +2.4 m/s ( +2.1 m/sQuestion 32 (1 point) An 18,000 kg freight car travelling 1.75 m/s[E] collides with a 27,000 kg freight car at rest. After the collision, the freight cars stick together. What is the velocity of the freight cars after the collision? ( 1.50 m/s [E] ( 0.70 m/s [E] 2.00 m/s [E] ( 0.50 m/s [E]Question 33 (1 point) An egg test dummy is fitted with a helmet, sealed in a plastic bag, and attached to a swing with a clamp. These items have a mass of 0.090 kg. This mass is pulled back to a height of 0.55 m. The mass is then released and allowed to swing down and collide with a cement block. What is the speed of the mass at the moment before impact? 3.28 m/s 4.65 m/s 1.64 m/s 10.8 m/sQuestion 34 (1 point) A UBU-kg egg test dummy is fitted with a helmet and attached to a swing. This egg test dummy is pulled back and released, allowing it to collide with a cement block. The impulse on the egg test dummy is - 0.39 Nx s over an interval of (3.050 5. What is the magnitude of the force on the egg test dummy during this time interval? 0 T8 N O 3.5 N O 1.8 N O 2.0 N Question 35 (1 point) A high-performance car initially travelling 97.2 km/h came to a stop in just 2.9 s. The mass of the car and its contents was 1850 kg. What was the magnitude of the average net force (braking force) on the car while it decelerated? 5.9 104 N 4.9 ' 104 N 1.7 10# N 1.8 104 NQuestion 36 [1 point] A motorcycle and its rider have a combined mass of 230 kg. The engine generates an applied force of 10m} N[E]. If the force of friction opposing the motorcycle is 320 MW], what is the acceleration of the motorcycle and its rider? O 2.96 W52[W] Q 5.74 maa] Q 2.95 W52[E] Q 5.7M m52[w1 Question 37 (1 point) A 500-kg vehicle experiences a change in momentum of + 356 kgxm/s over a time interval of 5.81 s. What is the force on the vehicle during this time? + 61.3 N 86.1 N[ forward] O+ 35.6 N 29.1 N [forward] Question 38 (1 point) In which class(es) of collisions will the occupants of a vehicle likely be injured? O secondary and tertiary O tertiary O secondary O primaryQuestion 39 [1 point] How do shock-absorbing bumpers, collapsible frames, and erumplc zones reduce injuries? C) The}.r increase the stopping time and maintain the change in momentum so the force generated during the _ impact decreases. ("j They decrease the stepping time and the change in momentum so the force generated during the impact decreases. ("j The}.r increase the stepping time and the change in momentum so the force generated during the impact _ increases. () The}r decrease the stopping time and maintain the change in momentum so the force generated during _ the impact increases. Question 40 (1 point) Which statement correctly expresses Newton's third law of motion? O An object will accelerate in the direction of the net force on the object. They decrease the stopping time and the change in momentum so the force generated during the impact decreases. O none of the above O Whenever one object exerts a force on a second object, the second object exerts an equal but opposite force on the first object. Question 41 (1 point) A cart with a mass of 10 kg has 600 J of kinetic energy. Knowing that Ex=Ep, to what vertical height will the cart rise on the ramp? 6.1 m O 98.1 m 9.81 m 60 m
