Is a moving car in motion?
Is a moving car in motion? Hint: An object is said to be in motion, if its position changes with time. A vehicle moving on a straight road changes its position every second, hence we can infer that the vehicle is...

What is the coefficient of a car moving with a speed of 20m s?
What is the coefficient of a car moving with a speed of 20m s? A motor car is moving on a straight horizontal road with a speed of 20 m/s. The coefficient of friction between the tyres and the road is...
What is the final velocity of a car that accelerated 10m s 2 from rest and traveled 180m?
What is the final velocity of a car that accelerated 10m s 2 from rest and traveled 180m? What is the final velocity of a car that accelerated 10 m/s2 from rest and traveled 180m? V2=u2+2ad=zero2+2*10*180, v2=3600, so v=60 m/s. When...
When a car’s velocity is positive and its acceleration is negative what is happening to the car’s motion?
When a car’s velocity is positive and its acceleration is negative what is happening to the car’s motion? Explanation: The car’s rate of change of position is decreasing. The car is moving but its rate of position increase is coming down....
What is the initial velocity of a car which is stopped in 10 seconds by applying brakes?
What is the initial velocity of a car which is stopped in 10 seconds by applying brakes? Hence, the initial velocity of the car is 25 m/s. Q. A car is retarded by applying brakes at the rate of 2 m/s2...
What happens when a car moves at constant speed?
What happens when a car moves at constant speed? Answer and Explanation: A car moving at a constant speed is in dynamic equilibrium, meaning that the forces acting on it are in balance. If the car engine stopped, however, there is...
What is a car moving with constant speed?
What is a car moving with constant speed? A car moves with constant speed on a straight path. So it is said to be in rotatory motion. What happens when a car moves at constant speed? Answer and Explanation: A car...
How to find initial velocity of a car which is stopped in 10 seconds?
How to find initial velocity of a car which is stopped in 10 seconds? v=u+at. ⇒ 0=u+(−2.5)×10. ∴ u=25m/s. When a car starts from rest and attains a velocity of 10 meters per second in 40 seconds? Expert-Verified Answer A driver...
What was the acceleration of the car moving initially at 30 m s comes gradually to a stop in 900 m?
What was the acceleration of the car moving initially at 30 m s comes gradually to a stop in 900 m? Expert-Verified Answer. The acceleration of the car is 0.5 meters per seconds square. Given the following data: Initial velocity, U...
When a car drives along a straight line at a constant speed then the car is accelerating?
When a car drives along a straight line at a constant speed then the car is accelerating? Answer and Explanation: Constant speed along a straight line is equivalent to constant velocity hence zero acceleration. See Figure (a). What do you say...
