- Question 9 (1 point) Compared to a sports car moving at 30 km per hour . the same sports car moving at 90 km per hour has __ a three times as much momentum b a decrease in momentum C the same momentum d twice as much momentum Question 10 (1 point) During the wall vs. bed sheet experiment, a 0 .03 kg egg is thrown at the wall with a force of 6N. The time of impact was 0.06 seconds, what was the impulse exerted on the egg. a 120Ncdot s b 0.36Ncdot s C 3.6Ncdot s d 12Ncdot s
- How long does it take a 2000-Kg car to stop from a velocity of 35m/s if a braking force of 4000 Newtons is used? p=mv m_(1)v_(1f)+m_(2)v_(2i)=m_(f)v_(1f)+m_(2)v_(2f) 10 seconds b 17.5 seconds 70 seconds d B.75 seconds Question 23 (1 point) Sug
- Problem 1 Ha-Joon (d) clays tennis throws a boll straight up into the air from the ground with an initial velocity of 2 meters per second during a surt. The height of the ball at any time t (in seconds) is given by the equation: h(t)=-t^2+2t+1.5 where (t) is the height of the tennis ball in meters. Questions: 1. How long will it take for the tennis ball to reach its maximum height? 2. What is the maximum height the tennis ball will reach? 3. Assuming Ha-loon (9) does not to hit the tennis ball during the surf, after how many seconds will the tennis ball hit the ground? (Round to the nearest 10^m second.)
- Question 11 (1 point) Rank the following in terms of greatest momentum to least. 1. A 5000 kg car in the parking lot 2. A 40 kg person jogging at 6m/s A 50 kg table being pushed at 2m/s 4.A 2 kg rabbit sprinting at 15m/s Question 12 (1 point) Impulse is defined as the force exerted on an object over a given distance.
