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?

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 car moving on a straight road increases linearly according to the equation?

The velocity of a car moving on a straight road Increases linearly according to equation, v = a + bx, where a & b are positive constants. The acceleration in the course of such motion: (x is the distance travelled) (1) increases!

How do you find initial speed with height and distance?

How to find speed with initial velocity acceleration and distance?

When a vehicle is moving on a road in a straight line with uniform velocity?

Since the vehicle is moving with uniform velocity, thus its acceleration must be zero. The friction force exerted by the road on its tires equals the force provided by its engine. So, the acceleration of the vehicle is zero and thus the vehicle moves with uniform velocity. Was this answer helpful?

When a car moves in a straight line at a constant speed?

A car moves with constant speed on a straight path. So it is said to be in rotatory motion.

When the speed of an object moving in a straight line is increasing?

An object moving at constant acceleration has an increasing speed per given time interval. This means that its initial acceleration, or the acceleration at the start of its motion, is the same as its terminal acceleration, or the acceleration at the end of its motion.

Is velocity same as speed?

Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

What is initial speed formula?

The first formula to find initial velocity is u = v – at.

Is initial speed the same as initial velocity?

Since speed is a scalar quantity, it doesn’t have a direction associated with it and instead is completely defined by a magnitude. In the case of the car from this question, we have defined 𝑢 as the magnitude of the initial velocity, and that will also be equal to the car’s initial speed.

What are the 3 formulas for velocity?

• v = u + at.
• v² = u² + 2as.
• s = ut + ½at²

What are the 4 equations for acceleration?

Variable	Equation
Velocity	v=u+at
Displacement with positive acceleration	s=ut+21at2
Displacement knowing initial and final velocities	s=21(u+v)t
Velocity squared	v2=u2+2as

What is the symbol for final velocity?

v denotes final velocity, a denotes acceleration, and t is the time taken.

What is the average speed of an object that travels 16 m in 4 second and then another 16 Metre in 2 second?

Hence, the average speed of the object is 5.33m/s. Q. An object travels 16 m in 4 s and then another 16 m in 2 s. What is the average speed of the object?

How far would a car travel in 4 seconds if it is moving with a speed?

A car travelling with a speed of 45 km/h will travel 45*1000*4/3600 = 50 m in 4 seconds.

What is the speed of a car moving at 50 km per hour returns on the same route with a speed of 40km hr?

Average speed=1+1(1/50)+(1/40)=44.44m/s.

What is the average speed of an object that travels 40 m in 5 seconds and then another 80 Metres in 5 seconds?

Hence, the average speed of the object is 12m/s.
