. Two cars emerge side by side from a tunnel. Car A is traveling with a speed of 60 km h and has an acceleration of 40 km h min.
Car B has a speed of 40 km h and has an acceleration of 60 km h min. Which car is passing the other as they come out of the tunnel? Explain your reasoning.
You are driving along Lawrence Ave. at 60 km/h. You see the traffic light ahead is still green and decide
to speed up to try to make it through the intersection before it turns red (poor decision!). Your car
accelerates at 1.3 m/s. You reach the light after accelerating for 4.3 seconds. What is your speed at
the light in m/s?

- You decide to drop a water balloon on a friend as a horribly inconsiderate prank that they shall never forgive you for. You climb onto an overpass near their favorite bike trail and release the balloon from rest some 7.7 m above the ground. If your friend is riding their bike at 11.4 m/s, how far out must they be from the overpass when you drop it? Assume your result is in m. DO NOT include units with your numerical answer.arrow_forwardVin Vout tunnel a=4 m/s? A car undergoing uniform acceleration, a=4.0 m/s², is travelling at a velocity of 40. m/s as it enters a tunnel. The positive direction is defined to the right. When the car exits the tunnel, its velocity is 72m/s. The average velocity of the car while in the tunnel is: 56 m/s 72 m/s 32 m/s 60 m/s 39 m/sarrow_forwardSome troublemaking kids are dropping water balloons from the roof of your apartment building. You are in your fifth-floor room and your window is 25 m above the sidewalk outside. You look outside and see that each balloon hits the pavement 1.5 s after passing your window. Express answers using 2 significant figures. a) How fast are the balloons traveling when they pass your window? b) Assuming the balloons are being released from rest, from what height above your window are they being released? c) If you threw a balloon upwards from your window with an initial speed of 6.5 m/s, would you be able to get it to the roof?arrow_forward
- You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.56 s, and the velocity of the car decreases to +4.84 m/s. The car’s deceleration has a magnitude of 3.67 m/s2 during this time. What is the car’s displacement?arrow_forwardYou and your family are going on a road trip to visit your recently married cousin in B.C. The total round trip distance is 2100 km. On the way to B.C., you encounter no setbacks and you are able to drive on average at a constant speed. On the way home from B.C., you encounter a snowstorm and your mom has to slow down to avoid getting into an accident. Thus, your average speed decreases by 10 km/h. If the total driving time was 42 hours, what was your average speed on the way to B.C.? Recall distance = speed x time.arrow_forwardAn airplane is initially traveling with a velocity of 55.0 m/s due east when a gust of wind causes the airplane to have an acceleration of 40.0 m/s² due north. What is the airplane's new total speed after 6.0 s? [Hint: Draw a picture.] O 174.6 m/s O 55.0 m/s O 184.4 m/s O 262.5 m/s O 246.2 m/sarrow_forward
- A student begins at rest and then walks north at a speed of v1 = 0.55 m/s. The student then turns south and walks at a speed of v2 = 0.53 m/s. Take north to be the positive direction. If the student travels in the stated directions for 30.0 seconds at speed v1 and for 20.0 seconds at speed v2, what is the net displacement, in meters, during the trip? If it takes the student 5.0 s to reach the speed v1 from rest, what is the magnitude of the student’s average acceleration, in meters per second squared, during that time?arrow_forwardA small block has constant acceleration as it slides down a frictionless incline. The block is released from rest at the top of the incline, and its speed after it has traveled 6.00 mm to the bottom of the incline is 3.80 m/sm/s. A). What is the speed of the block when it is 4.60 mm from the top of the incline? Express your answer with the appropriate units.arrow_forwardCheetahs can accelerate to a speed of 20.2 m/s in 2.65 s and can continue to accelerate to reach a top speed of 29.0 m/s . Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +? direction point in the direction the cheetah runs.Express the cheetah's top speed ?top in miles per hour (mi/h) .Starting from a crouched position, how much time ?accel does it take a cheetah to reach its top speed and what distance ? does it travel in that time?arrow_forward
