a few things missing:
- How fast is the acceleration?
- How long does it take to go from 4ms to 20ms?
The distance the car travels during the acceleration can be calculated using the formula: distance = (initial velocity)(time) + 0.5(acceleration)(time)^2. Plug in the values: initial velocity = 0 m/s, final velocity = 40 m/s, time = 8 s. Calculate the distance traveled during the acceleration.
The final velocity of the object is 4 m/s.
Sydney's car accelerates at 5.9 m/s^2, while Sean's car accelerates at 3.6 m/s^2. Sean starting 1.0 second early gives him an initial distance advantage, but Sydney's higher acceleration rate means she will catch up and overtake Sean at some point during the race. The exact point of overtaking can be calculated by comparing their positions over time.
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.
The displacement-time graph for uniformly accelerated motion is a curve that is concave upwards. It starts with a less steep slope and gradually becomes steeper as time progresses due to the acceleration being constant.

6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.
Question:A car starts from rest and accelerates uniformly. It acquires a velocity of 72 km/hr in 10 seconds. What is its acceleration?Answer:Since the car is starting fom rest, its initial velcity (u) = 0Final velocity (v) = 72 km/hr =20 m/sTime taken for change of velocity (t) = 10 secondsAcceleration, a = (v-u)/t = (20-0)/10 = 20/10 = 2 m/s2
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
Fishing tends to start out slow, then accelerates quickly through the month of August.

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.
