An engineer is setting a speed limit on a road. She wants a car to be able to stop in 147ft and knows that the maximum rate at which a car can safely
brake is 20.0ft/s?
What initial speed (in given units) will allow the car to come a stop at the stop
sign when braking with this acceleration?
mph
Could a car traveling 60mph come to a stop before the stop sign?
chock

Aforce of 8,480 n is applied to a cart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?

In the united states, tornadoes generally occur because of the freezing of ocean water underwater earthquakes meeting of cool and warm air masses shifting of warm and cool ocean currents

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
