WebAverage speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense. WebApr 13, 2024 · Explanation: We have the position as the function s(t) = t3 +8t2 − t. Velocity is the rate of change of position over time, so its the derivative of the function. ∴ s'(t) = 3t2 +16t − 1 So at t = 2, the velocity is, s'(2) = 3 ⋅ 22 + 16⋅ 2 − 1 = 3 ⋅ 4 + 32− 1 = 12 +32 − 1 = 44 −1 = 43 Answer link trubyinc.comWebThe acceleration is the change in velocity ÷ time, which is -8 m/s ÷ 2 s = -4 m/s 2.

"WebFeb 2, 2024 · You can express acceleration by standard acceleration, due to gravity near the surface of the Earth, which is defined as g = 31.17405 ft/s² = 9.80665 m/s². For example, if you say that an elevator is moving upwards with the acceleration of 0.2g, it means that it accelerates with about 6.2 ft/s² or 2 m/s² (i.e., 0.2 × g ).

WebThe motorboat decreases its velocity to zero in 6.3 s. At times greater than this, velocity becomes negative—meaning, the boat is reversing direction. (b) Position of the motorboat as a function of time. At t = 6.3 s, the velocity is zero and the boat has stopped. Weba. Convert the velocities to $\mathrm{m} / \mathrm{s}$, then make a graph of velocity versus time. Based on your graph, is the acceleration constant? Explain. b. Draw a smooth curve through the points on your graph, then use your graph to estimate the car's acceleration at $2.0 \mathrm{~s}$ and 8.0 s. Give your answer in SI units.
