Please ty.pe or writ.e clearly
1.
A car that is initially moving at 7.50 m/s begins to accelerate forward uniformly at 0.550 m/s2. (a) How long after beginning to accelerate does it take the car to move 3.50 km? (b) How fast is the car moving just as it has traveled 3.50 km?
2.
At the instant a traffic light turns green, a car that has been waiting at the intersection starts ahead with a constant acceleration of 2.00 m/s2. At that moment a truck traveling with a constant velocity of 15.0 m/s overtakes and passes the car.
- Calculate the time necessary for the car to reach the truck.
- Calculate the distance beyond the traffic light that the car will pass the truck.
- Determine the speed of the car when it passes the truck.
3.
The captain orders his starship to accelerate from rest at a rate of "1 g" (1 g = 9.8 m/s2). How many days does it take the starship to reach 10% the speed of light? (Light travels at 3.0 108 m/s.)
4.
The position x(t) of a particle as a function of time t is given by the equation x(t) = (3.5 m/s)t - (5.0 m/s2)t2. What is the average velocity of the particle betweent = 0.30 s and t = 0.40 s?
5.
V (m/s) The graph in the figure represents the velocity of a particle as it travels along the x-axis. What is the average acceleration of the particle between t = 2.0 s and t = 4.0 s? 4.0 2.0 1.0 2.0 3.0 4.0 -t (s) -2.0 -4.010. The figure shows a graph of the position of a moving object as a function of time. What is the velocity of the object at each of the following times? (a) At t = 1.0 s (b) At t = 2.5 s (c) At t = 4.0 s (d) At t = 5.5 s Position (m) 50 40 30 20 10 1.0 2.0 3.0 4.0 5.0 6.0 Time (s)The graph in the gure shows the position of a particle as it travels along the x-axis. What is the magnitude of the instantaneous velocity of the particle when t = 1.0 s? .r(m) [Step by Step Solution
