7. A car starts from rest and moves with a constant acceleration of 1.5 m/s² until it achieves a velocity of 25 m/s. It then travels with constant velocity for 60 seconds.  Determine the average speed of the car

A satellite orbiting at an altitude of 500 kilometres travels around the earth 15 times in 24 hours. Determine the linear velocity of the satellite in km/h if the average diameter of the earth is approximately 7918 miles.

A particle travels along a straight-line path such that in 4 s it moves from an initial position S_C=-8 m to a position S_Bd=+3 m. Then in another 5 s it moves from S_B to S_C=-6 m. Determine the particle's average velocity and average speed during the 9-s time interval.

Q22. As shown in the image below, a motorcycle travels along circular path from point A to point B. Its decreases at at = − (C. s) m/s², where Cis a constant and s is the distance (in m) traveled along the path measured from point A. If the constant C is 0.002, and the motorcycle has speed of 32 m/s at point A, determine the magnitude of its total acceleration (in m/s2) at point B. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. .A Your Answer: Answer A 300 m n 90° B
