How can a vehicle at the same time have a constant speed but changing velocity?
Speed is a scalar quantity (direction does not matter) and velocity is a vector quantity) ie velocity means speed in a specific direction. If you are changing direction (turning) in a car, your speed is the same, while your velocity changes.
Is average speed of a vehicle a vector or scalar quantity?
In physics:If you talk about speed, that refers to a scalar quantity.If you talk about velocity, that refers to a vector quantity.
Velocity equals speed and what?
Velocity= Distance/time or V=D/T. there is a triangle to help remember this D ----- V | T permutations: V=D/T D=V X T T=D/V
How many feet will it take you to stop your car if you going 60 mph?
Without knowing either the rate of negative acceleration or the time it takes for the car to stop, this question cannot be answered. There are three kinematic equations that could be used to answer this question. They are as follows:d = (v_i)(t) + (1/2)(a)(t^2)d = (v_i + v_f)/2 x tV_f^2 = v_i^2 + 2ad, solve for dIn these equations, d is displacement, a is acceleration, t is time, v_i is initial velocity, and v_f is final velocity.
When a vehicle is slowing down what changes its momentum and kinetic energy as force of brakes is an internal force?
Brakes absorb the kinetic energy in the form of heat and sometimes sound. When hot enough brakes can emit light.
A vehicle's momentum depends on its?
A vehicle's momentum depends on its mass and velocity. The momentum of a vehicle is the product of its mass and its velocity. The larger the mass or velocity of a vehicle, the greater its momentum.

What is the acceleration of a vehicle that changes velocity from 100km to a dead stop in 30seconds?
It wont be accelerating at all, its in the process of stopping you ignorant sh it
Zero velocity means vehicle must be stationary?
Zero velocity means that the vehicle and the person who is measuring the velocity are moving together.
How the mechanical Advantage of a wheel And axle changes as the size of the wheel increases.?
The velocity factor of a wheel depends on its diameter. If we take the velocity factor as a measure of how far the vehicle moves in one revolution of the wheel, then it is equal to the circumference of the wheel, which is pi times the diameter.

What happens when you increase the velocity of the vehicle?
Your speed increases
A vehicle accelerates uniformly from a speed of 4.0ms to a speed of 12ms in 6.0s. What is the vehicles acceleration?
4/3 ms-2.
What is the acceleration of vehicle moving with uniform velocity?
It has zero acceleration!!
What is the acceleration of a vehicle that changes its velocity from 500 kmh to a dead stop in 20 s?
v=u+(a*t) 0=500+(a*20) (0-500)/20=a a=-25(km/h)/s
What is the initial velocity of the car?
The speed of the vehicle before deceleration or braking.
