The diameter of a tire is 70.5 cm uniformly from Find the number of revolutions the tire makes during this motion, assuming no slip- ping. Answer in units of...
An objects begins motion with an initial speed of 6.00m/s and accelerates uniformly to a speed of 8.00m/s at time t=1.00s. How far does the object travel at time t=4.00s?
A particle, starting at rest, accelerates at 5 m/s2 for 10s. It then decelerates to 30 m/s over a period of 10s. The particle then moves at a constant speed for 20s before decelerating to zero over a period of 5s. Plot the velocity and acceleration of the particle as functions of time. What is the total distance traveled by the particle?
A car accelerates uniformly from rest and reaches a speed of 17.8 m/s in 7.1 s. The diameter of a tire is 69.7 cm. Find the number of revolutions the tire makes during this motion, assuming no slipping. Answer in units of rev
A particle moving along the x axis in simple harmonic motion starts from its equilibrium position, the origin, at t = 0 and moves to the right. The amplitude of its motion is 3.50cm, and the frequency is 2.30 Hz. (a) Find an expression for the position of the particle as a function of time. (Use the following as necessary: t. Assume that x is in centimeters and t is in seconds. Do not include units in your answer.) x...
