Concept explainers
As a car accelerates, it does not accelerate at a constant rate; rather, the acceleration is variable. For the following exercises, use the following table, which contains the acceleration measured at every second as a driver merges onto a freeway.
Time (sec) | Acceleration (mph/sec) |
1 | 11.2 |
2 | 10.6 |
3 | 8.1 |
4 | 5.4 |
5 | 0 |
251. [T] Using your velocity equation from the previous exercise, find the corresponding distance equation, assuming your initial distance is 0 mi. How far did you travel while you accelerated your car? (Hint: You will need to convert time units.)

- For the following exercises, find the slope of the lines that pass through each pair of points and determine whether the lines are parallel or perpendicular. 30. F=ma indicates that force (F) equals mass (m)times acceleration (a). Find the acceleration of a mass of 50 kg if a force of 12 N is exerted on it.arrow_forwardFor the following exercises, use Kepler’s Law, which states that the square of the time, T, required for a planet to orbitthe Sun varies directly with the cube of the mean distance. a. that the planet is from the Sun. 46. Using the Earth’s time of 1 year and mean distance of93 million miles, find the equation relating T and a.arrow_forwardI need help finding the distance the stick traveled. It’s average acceleration is 1.5 mph.arrow_forward
- The position of a hummingbird flying along a straight line in t seconds is given by S(t) = 3t³ – 32t meters. Determine the acceleration of the bird at t = 6 sec.arrow_forwardThe position of a hummingbird flying along a straight line at t seconds is given by s(t) = 3t3 -7t in meters. Determine the acceleration of the bird when the velocity equals 0.arrow_forwardFind the velocity and speed when t=3arrow_forward
- A UFO (Unidentified Flying Object) is moving in such a way that the vertical distance between the ground and the UFO is given by x(t) = t³ + 41², where x is measured in metres and t is measured seconds. Find the average velocity of the UFO in the first 3 seconds. Select one: O 21 m/s 41 m/s 3 O 41 m/s O 63 m/sarrow_forwardAn object is dropped from a tower, 182 ft above the ground. The object's height above ground t sec into the fall is s = 182 – 162. a. What is the object's velocity, speed, and acceleration at time t? b. About how long does it take the object to hit the ground? c. What is the object's velocity at the moment of impact? ..... The object's velocity at time t is The object's speed at time t is ft/sec. The object's acceleration at time t is ft/sec². (Simplify your answer.) It takes sec for the object to hit the ground. (Round to the nearest tenth.) The object's velocity at the moment of impact is ft/sec. (Round to the nearest tenth.)arrow_forwardUse a(t)= - 32 ft/sec? as the acceleration due to gravity. A ball is thrown vertically upward from a platform 3 feet above the ground. When t =1 second, the velocity is 64 feet per second. What is the maximum height of the ball? The ball will reach a maximum height of feet.arrow_forward
