A car traveling initially at +5.7 m/s acceler- ates uniformly at the rate of +0.79 m/s2 for a distance of 262 m. What is its velocity at the end of the accel- eration? Answer in units of m/s What is its velocity after it accelerates for 132 m? Answer in units of m/s What is it...
With an average acceleration of −0.96 m/s2, how long will it take a cyclist to bring a bicycle with an initial speed of 14.8 m/s to a complete stop? Answer in units of s
A window washer drops a brush from a scaf- fold on a tall office building. What is the speed of the falling brush after 2.7 s? (Neglect drag forces.) The acceleration due to gravity is 9.8 m/s2 . Answer in units of m/s How far has it fallen in that time? answer in units of m
A car travels along a straight stretch of road. It proceeds for 11.9 mi at 58 mi/h, then 29.4 mi at 44 mi/h, and finally 36.9 mi at 31.6 mi/h. What is the cars average velocity during the entire trip? Answer in units of mi/h
