Question 1 (1 point) A billiard cue ball strikes a stationary billiard ball so that it glances off its original path by an angle of 30. If its original path is considered as the positive x-direction, then the horizontal component of the velocity of the deflected cue ball is v sin 30. Question 2 (1 point) A baseball player usually catches a ball by moving their hand backwards in the direction of the ball's motion. This reduces the force of impact of the collision because the momentum change is decreased. Question 3 (1 point) A mass is suspended vertically by a spring If the mass is allowed to fall freely, the maximum extension of the spring is 5 cm. If the spring is first compressed by 2 cm before the spring is allowed to fall freely, which statement is correct? 0 The spring will remain in the compressed position. 0 The maximum extension of the spring is equal to 5 cm. 0 The maximum extension of the spring is less than 5 cm. 0 The maximum extension of the spring is more than 5 cm. Question 4 (1 point) Force is applied to an object. In which case does zero work occur? 0 The object does not move. A billiard cue ball having velocity of 5.0 cm/s and a mass 0.17 kg approaches a stationary red billiard ball of mass 0.16 kg. If the cue ball is stationary after their collision, what is the new velocity for the red ball? 2.5 m/s 4.7 m/s 4.9 m/s 5.3 m/s Question 9 (1 point) A 2000 kg car travelling at 30 km/h [N] has the same momentum as a locomotive travelling at 0.5 km/h [N]. True False Question 10 (1 point) Ball A travelling with velocity, v, collides head-on with stationary ball B. If the mass of ball A is much smaller than the mass of ball B, what is the velocity of ball B immediately after impact? (It remains stationary.) O (the initial velocity of ball A) O 2v (twice the initial velocity of ball A) 0.5V (half the initial velocity of ball A)Question 7 (1 point) A child on a pogo stick decreases their elastic potential energy as they compress the stick downward. Question 8 (1 point) A billiard cue ball having velocity of 5.0 cm/s and a mass 017 kg approaches a stationary red billiard ball of mass 0.16 kg. If the cue ball is stationary after their collision, what is the new velocity for the red ball? Question 9 (1 point) A 2000 kg car travelling at 30 km/h [N] has the same momentum as a locomotive travelling at 0.5 km/h [N]. Question 4 (1 point) Force is applied to an object. In which case does zero work occur? 0 The object does not move. 0 The force is perpendicular to the direction of motion. 0 The magnitude of the force on the object is zero. 0 all of the above Question 5 (1 point) A bungee jumper is prepared to begin her fall. At this time, the jumper has more kinetic energy than potential energy. Question 6 (1 point) Two equal mass eggs are dropped 50 cm, one onto concrete and the other onto a soft foam. The momentum of the first egg is greater than the momentum of the second one. Question 7 (1 point) A child on a pogo stick decreases their elastic potential energy as they compress the stick downward
