A motor scooter travels east at a speed of 11.6 m/s. The driver then reverses direction and heads west at 17.2 m/s. What is the change in velocity of the scooter? Give magnitude (enter first) and direction. (east or west?)

A man walks forward on a bus. To a stationary observer, the bus moves east at a speed of 18 m/s. If the man moves 1.5 m/s east relative to the bus, what is his velocity in the frame of reference of a stationary observer?A.18 m/s eastB.16.5 m/s eastC.19.5 m/s eastD.16.5 m/s westSUBMITarrow_backPREVIOUS

A wheel initially (at t = 0) has an angular velocity of 18 rad/s.It has a constant angular acceleration with a magnitude of 2.0 rad/s2 and at t = 0 the angular velocity is decreasing.At what time t is the angular velocity equal to 18 rad/s in the direction opposite to the initial angular velocity?Express your answer in seconds.

A stuntman drives a dirt bike on a curved track with a radius of 16.9 m. If he starts from rest and accelerates at 1.06 m/s2, at what time will the magnitude of the total acceleration of the bike be 5.74 m/s2? (Hint: the tangential acceleration will stay constant at 1.06 m/s2.)

Kirtaan walks from his house with a velocity of 2 m/s East for 30 seconds and then walks with a velocity of 8 m/s South for 10 seconds.  At the end of these 40 seconds, how far from his house is Kirtaan?
