1. If you are driving 85 km/h along a straight road and you look to the side for 2.0s, how far do you travel during this inattentive period? Assume that your speed remains constant.

2. A child, who is 46 m from the bank of a river, is being carried helplessly downstream by the river's swift current of 1.5 m/s. As the child passes a lifeguard on the river's bank, the lifeguard starts swimming in a straight line (perpendicular to the bank) until she reaches the child at a point downstream. If the lifeguard can swim at a speed of 2.2 m/s relative to the water, how long does it take her to reach the child? How far downstream does the lifeguard intercept the child?

A 1500 kg automobile travels at a speed of 85 km/h along a straight concrete highway. Faced with an emergency situation, the driver jams on the brakes, and the car skids to a stop. (a) What will be the car's stopping distance for dry pavement (µ = 0.85)? (b) What will be the car's stopping distance for wet pavement (µ = 0.60)?

A tourist is driving a car along a straight road at a constant speed of 22.5 m/s. Just as she passes a law officer parked along the side of the road, the officer starts to accelerate 2.50 m/s2 to overtake her. Assume that the officer maintains this acceleration. (a) Determine the time it takes the officer to reach the tourist (in s). 18 s (b) Find the speed of the officer as he overtakes the tourist (in m/s). 45 m/s...

Consider driving a car in one direction along a straight road for 10 minutes. You start from rest. During the first 1 minute, you speed up with constant acceleration until you reach 60 m/s. During the next 5 minutes, you maintain constant speed at 60 m/s. During the final 4 minutes, you have constant negative acceleration (i.e. deceleration) until you are not moving. How far in total did you travel during the whole 10 minutes? Express your answer in units...

A 3000 kg truck is driving along a straight road at a constant speed of 60 km/hr. A 800 kg car starts accelerating from stationary as the truck goes past it. Ignore air resistance. (a) How far has the truck travelled after 5 minutes? Give your answer in kilometres. -2 (b) If the car accelerates at 6 ms (c) How far will the car have travelled when it reaches this speed? (d) What is the force associated with of motion...

You are driving up a long, inclined road. After 1.40 mi you notice that signs along the roadside indicate that your elevation has increased by 530 ft . You may want to review (Pages 62 - 65) . What is the angle of the road above the horizontal? How far do you have to drive to gain an additional 130 ft of elevation?

a stunt driver's car is moving at 24.2 m/s along a straight road. The road comes to an abrupt stop 21.2 m before a drop off. The coefficient of friction of the road is 0.712, and the coefficient of friction of the dirt between the road and the drop off is 0.426. What is the minimum distance at which the driver can behin to apply the brakes and still prevent himselff from going over the edge?
