How far does a car travel when it starts from rest and accelerates to a certain speed?
The distance a car travels when it starts from rest and accelerates to a certain speed depends on the acceleration of the car and the time it takes to reach that speed. The formula to calculate this distance is d 0.5 a t2, where d is the distance, a is the acceleration, and t is the time taken to reach the speed.
Why does a package on the seat of a bus slide backward when the bus accelerates quickly from rest?
The package on the seat slides backward because of inertia. As the bus accelerates forward, the package wants to remain at rest (due to its initial inertia), causing it to move in the opposite direction of the bus's acceleration. This results in the package sliding backward relative to the bus.
Does a car have negative acceleration when leaving a garage?
No, a car leaving a garage typically experiences positive acceleration as it accelerates from rest to exit the garage. Negative acceleration, also known as deceleration or braking, occurs when the car slows down or stops.
What is the final velocity of an object that starts from rest and accelerates uniformly with an acceleration of 2 m/s2 over a distance of 2 meters?
The final velocity of the object is 4 m/s.
What is law of acceleration and example?
The law of acceleration states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that the greater the force applied to an object, the greater its acceleration will be, and the more massive an object is, the less it will accelerate for a given force. An example is when a car accelerates from rest when the driver steps on the gas pedal.
Is a car accelerates from rest to 27M/S 22.9 seconds what is the average acceleration?
the acceleration of the car is 1.179m/s/s given the formula provided.

How does your weight mass and the normal force exerted by the floor change when you are in an elevator that starts from rest and accelerates upward?
When you are in an elevator that starts from rest and accelerates upward, your weight (mass times gravitational acceleration) remains constant because your mass does not change. However, the normal force exerted by the floor increases during the upward acceleration. This is because the elevator's acceleration adds to the gravitational force, resulting in a greater normal force acting on you, which can be felt as an increase in apparent weight.
How many meters does a car travel that starts from rest and accelerates for 4.7 seconds with an acceleration rate of 3.6 meters per second squared?
60.912 meters in that time
What is the speed of a skateboarder who accelerates from rest for 3 seconds down a ramp at an acceleration of 5 mss?
Speed = (initial speed) plus (acceleration) x (time) = 0 + (5) x (3) = 15 meters per second.
A car accelerates from rest and accelerates at 3 ms-2 how long it will take to reach a velocity of 30ms-1?
Acceleration = (change in speed) / (time for the change)3 = (30) / (time)3 x (time) = 30time = 30/3 = 10 seconds

How your weight mass and the normal force exerted by the floor change when you are in an elevator that starts from rest and accelerates upward?
When an elevator accelerates upward from rest, your weight (the force due to gravity acting on you) remains constant, as it is determined by your mass and the acceleration due to gravity. However, the normal force exerted by the floor increases because it must counteract both your weight and provide additional force due to the upward acceleration of the elevator. Consequently, you would feel heavier during the upward acceleration, as the normal force exceeds your weight.

A dragster accelerates from rest to 402.3mpsec in 9.013sec calculate the rate of acceleration assuming this to be constant the maximum speed?
Since , V = u + at, we get , a = v - u /t = 402.3 - 0 /9.013 = 44.6355264617 ms-2 Therefore, acceleration = 44.6355264617 ms-2
