2. A car accelerates along a straight road from rest to 90 km/h in 5.0s. What is the magnitude of average acceleration in meters per second squared. 3. If you are driving 110km/h along a straight road and look to the side for 2.0s, how far do you travel during this inattentive period? 4. At highway speeds, a particular car is capable of accelerating at about 1.8m/s?. At this rate, how long does it take to accelerate from 80km/h to...
A car on a straight level road, starts from rest and accelerates to a speed of 1,846 ft/'s in 49 seconds. What is the car's average acceleration in ft/s??
The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...
A 1500-kg car starts from rest and accelerates uniformly to 18.0 m/s in 12.0 s over a dry concrete road. Assume that kinetic friction remains constant at 400 N during this time. – (a) Find the net work done on the car and the work done by the engine. – (b) How many revolutions does each tire make over the 12.0 s interval? What is the angular speed of the wheels when the car has traveled half the total distance?...
A car on a straight road first accelerates from rest to 20 m/s in 10 s, then travels at a constant velocity for 20 s, then slows down for 5 s and comes to stop. Find the total distance traveled by the car.
A truck accelerates uniformly from rest to 23.0 m/s in 5.4 s along a level stretch of road. Determine the average power in W) required to accelerate the truck for the following values of the weight (ignore friction) (a) 8.00 x 10' N (b) 1.50 X 10' N Supporting Materials Physical Constants Additional Materials Reading 1/1.5 points Previous Answers OSColPhys1 8.1.001. (a) Calculate the momentum of a 1600 kg elephant charging a hunter at a speed of 7.50 m ....
Consider the following situations: A car is moving along a straight road at a constant speed. A car is moving along a straight road while slowing down. A car is moving along a straight road while speeding up. A hockey puck slides along a horizontal icy (frictionless) surface. A hockey puck slides along a rough concrete surface. A cockroach is speeding up from rest. A rock is thrown horizontally; air resistance is negligible. A rock is thrown horizontally; air resistance...
A car accelerates uniformly from rest to 20.0 m/s in 5.6 s along a level stretch of road. Ignoring friction, determine the average power required to accelerate the car if (a) the weight of the car is 9.0 x 103 N and (b) the weight of the car is 1.4 x 104 N Please show the reasoning and solution.
A car is traveling along a straight road at a velocity of +28.1 m/s when its engine cuts out. For the next 2.97 seconds, the car slows down, and its average acceleration is . For the next 4.30 seconds, the car slows down further, and its average acceleration is . The velocity of the car at the end of the 7.27-second period is +21.3 m/s. The ratio of the average acceleration values is = 1.37. Find the velocity of the...
