5. An amateur ball player runs at an average Speed of 6.0 m/s between
home plate and first base and
9.0 m/s between first and second.
If the distance between the bases is
27.4 m and the base lines form an
angle of 90°, calculate his average
velocity. Include reference coordi-
nates in your answer.

What object a collides with object b and bounces back its final momentum is?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
