1: A woman backs her van out of her garage with a constant acceleration of 1.1 m/s². Assume that her initial motion is in the positive direction.

Part (b) If she then brakes to a stop in 0.85 s, what is her acceleration in meters per square second?

2: A driver in Germany is on a street that has a posted speed limit of v_m = 65 km/hr and is driving over the speed limit by v_c = 11 km/hr. A vehicle pulls out of a parking place into the street in front of the driver d = 11 m in front of the driver and stops there. The driver immediately slams on the brakes and begins decelerating at a rate of a_b = 3.5 m/s².

Part (c) Enter an expression for the time, t, it will take the driver to come to a stop after applying the brakes, in terms of the defined quantities

Part (d) How fast, in meters per second, is the driver driving when he hits the vehicle in front of him?

1. A wheel is turning about an axis through its center with constant angular acceleration. Starting from rest, at t=0, the wheel turns through 8.50 revolutions in t= 10.5 s . At 10.5 s the kinetic energy of the wheel is 34.0 J. For an axis through its center, what is the moment of inertia of the wheel? Express your answer with the appropriate units. 2.While redesigning a rocket engine, you want to reduce its weight by replacing a solid...
