A motorcycle has a constant acceleration of 4.33 m/s². Both the velocity and acceleration of the motorcycle point in the same direction. How much time is required for the motorcycle to change its speed from (a)44.7 to 54.7 m/s, and (b)74.7 to 84.7 m/s?

A car is traveling to the left, which is the negative direction. The direction of travel remains the same throughout this problem. The car's initial speed is 34.1 m/s, and during a 5.87-second interval, it changes to a final speed of (a)51.1 m/s and (b)30.6 m/s. In each case, find the acceleration (magnitude and algebraic sign)

You step onto a hot beach with your bare feet. A nerve impulse, generated in your foot, travels through your nervous system at an average speed of 139 m/s. How much time does it take for the impulse, which travels a distance of 1.73 m, to reach your brain?

26' A vehicle starting its motion from rest travels at a uniform acceleration of 5ms-2 for a certain time and

travels with the attained uniform velocity for another certain period of time. Then it decelerates uniformly at

5ms-2 and stops after a certain time. If the total time spent is 25s and the average velocity for the whole

motion is 20ms-1 , find the time that the vehicle travelled at uniform velocity.
