1. Equanne driving at 30 m/s. enters a one-lake tunnel. She then observes a slow moving van 155 m ahead travelling at 5 m/s. Equanne applies her brakes immediately only -2 m/s because the road is wet. Will there be collision? If yes, determine how far into the tunnel and at what time the collision occurs.? If N- determine the distance closest approach between Equanne's car and the van

Speedy Sue, driving at 30.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 155 m ahead traveling at 5.00 m/s. Sue applies her brakes but can accelerate only at 2.00 m/s2 because the road is wet. Will there be a collision? State how you decide. If yes, determine how far into the tunnel and at what time the collision occurs. If no, determine the distance of closest approach between Sues car and the van.
There is a 250-m-high cliff at Half Dome in Yosemite National Park in California. Suppose a boulder breaks loose from the top of this cliff. (a) How fast will it be going when it strikes the ground? (b) Assuming a reaction time of 0.300 s, how long will a tourist at the bottom have to get out of the way after hearing the sound of the rock breaking loose (neglecting the height of the tourist, which would become negligible anyway if hit)? The speed of sound is 335 m/s on this day.
A student writes, "A bird that is diving for prey has a speed of -10 m / s." What is wrong with the student's statement? What has the student actually described? Explain.
(a) Explain how you can determine the acceleration over time from a velocity versus time graph such as the one in Figure 2.56. (b) Based on the graph, how does acceleration change over time?
A particle starts from rest and accelerates as shown in Figure P2.20. Determine (a) the particles speed at t = 10.0 s and at t = 20.0 s, and (b) the distance traveled in the first 20.0 s. Figure P2.20
A tortoise can run with a speed of 0.11 m/s, and a hare can run 20 times as fast. In a race, they both start at the same time, but the hare stops to rest for 2.0 minutes. The tortoise wins by a shell (35 cm). (a) How long does the race take? s(b) What is the length of the race? m
Speedy Sue, driving at 32.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 165 m ahead traveling at 5.10 m/s. Sue applies her brakes but can accelerate only at −1.30 m/s2 because the road is wet. Will there be a collision? Yes or No If yes, determine how far into the tunnel and at what time the collision occurs. If no, determine the distance of closest approach between Sue's car and the van. (If no, enter "0" for the time.) distance ?m time ?s
1. Cars A and B approached each other on a straight road from points 450 m apart. Car A has an initial velocity of 70 kph and decelerates at the rate of 0.4 m/s". Car B has an initial velocity of 20 kph and accelerates at the rate of 0.3 m/s. After how many seconds will the two cars meet? 2. An elevator starting from rest at the first floor of a tall building accelerates uniformly at 0.5 m/s? for 4 seconds, then move at a constant speed for 10 seconds, then decelerate uniformly for 6 seconds until it stopped. If the floors are 3 m apart, at what floor did it stop?
A 1500kg sport car is moving westbound at 20m/s on a level road when it collided with a 4000kg truck driving east on the same road at 15m/s. The two vehicles remain locked together after the collision. a)what are is the magnitude of the velocity of the two vehicles just after the collision?
a motorist suddenly notices a stalled car and slams on the brakes, decelerating at the rate of 6.3 meter per second square. unfortunately, this isn't good enough, and a collision ensues. from the damage sustained, police estimate that the car was moving at 18km/h at the time of collision. they also measures skid marks 34m long. (a) how fast was the motorist going when brakes were first applied? (b) how much time was elapsed from the initial braking to the collision?
1. A car starts from rest and attains a speed of 50 m/s in 15 seconds. a. How far has the car travelled in 15 seconds? b. What is the speed of car if it travels 567 meters?
Speedy Sue, driving at 32.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 175 m ahead traveling at 5.30 m/s. Sue applies her brakes but can accelerate only at −1.10 m/s2 because the road is wet. Will there be a collision? If yes, determine how far into the tunnel and at what time the collision occurs. If no, determine the distance of closest approach between Sue's car and the van. (If no, enter "0" for the time.)
