Can a car travel eastward can its acceleration be westward explain your answer and use an example in your explanation? If a car is travelling eastward and slowing down, its acceleration is opposite to the direction of travel: its acceleration is westward. Was this answer helpful? What is the velocity of the 3 kg ball […]

Would a car moving away from you seem to have a higher or a lower pitch? It happens when either the source of the waves or the receiver of the waves is moving. The picture shows that the sound waves get compressed as the car moves toward you, creating a higher pitch sound. As the

What does in still air mean? IN GENERAL, still air means air with no wind and no vertical air motion. – quiet flyer. How does the pitch of a moving car horn sound to the person in front of it? As the car approaches listener A, the sound waves get closer together, increasing their frequency.

Can a car moving with speed V on a straight road can be stopped in distance D on applying brakes if the same car Hence, answer is 18d. A car moving with a speed of 40 km/h can be stopped by applying brakes at least after 2m. What is the speed V of a car

What is the physics of crumple zone? A change in “momentum” happens when a force is applied to an object that is moving or is able to move. The faster the change in momentum, the greater the force involved. Crumple zones do two things: they absorb energy by the crumpling, and slow down the collision

What is the initial speed of a car if it travels 50 m distance in 4 second with acceleration of 5 metre per second square? If a car travels 50 m distance in 4 s with a acceleration of 5 m/s2, then what was its initial speed? [Ans. 2.5 m/s] When the velocity of a

When brakes are applied on a moving vehicle? When brakes are applied to a moving vehicle, the distance it travels before stopping is called stopping distance. It is an important factor for road safety and depends on the initial velocity (v0) and the braking capacity, or deceleration, -a that is caused by the braking. What

What does a car moving at an average speed of 55.0 mi h for 4.25 h has traveled? Answer and Explanation: This means the car has travelled a distance of 234 mi in the given time interval. What is the average speed of a car moving at a speed of 50 km hr returns with

What is average speed of the car? It is calculated by dividing the total distance something travels by the total amount of time it spends traveling. For example, one can consider the car from earlier. If the car travels 70 miles in 2 hours, it would have an average speed of 70 / 2 =

What is a car moving with a constant speed? A car moves with constant speed on a straight path. So it is said to be in rotatory motion. How do you know if a car is moving at a constant speed? Constant speed means the speed does not change at all for each second of
