(20 points) A car starting from rest travels 220 m in 9.4 seconds with a constant acceleration. It then travels at a constant speed for another 12 seconds. After that, the brakes are applied and the car comes to rest an acceleration of 6.5 m/s2. A) Draw the motion diagram for the entire trip. B) What direction is the acceleration when the car is coming to rest? C) List all known variables with their values. D) What is the acceleration...

liysics ihematics ine Dimension Distance, Acceleration and Velocity Practice Problems A van travels at a constant speed of 18 m/s for 4.3 seconds. It begins to accelerate at a rate of 3.4 m/s2 for 5.1 seconds and then maintains that speed for another 15 seconds. Finally, it slows down to rest in 14.8 seconds. How far did the van travel during this time.

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 5.6 m/s2 for 3 seconds. It then continues at a constant speed for 7.8 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 178.16 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...

A truck covers 40.0 m in 9.45 s while uniformly slowing down to a final velocity of 2.35 m/s. (a) Find the truck's original speed. ________m/s (b) Find its acceleration. _________ m/s2 A car starts from rest and travels for 7.5 s with a uniform acceleration of +3.0 m/s2. The driver then applies the brakes, causing a uniform acceleration of −1.5 m/s2. If the brakes are applied for 2.0 s, determine each of the following. (c) How fast is the...

1. A car starts from rest and travels for 8.0 s with a uniform acceleration of +1.8 m/s2. The driver then applies the brakes, causing a uniform acceleration of −1.5 m/s2. If the brakes are applied for 2.0 s, determine each of the following. (a) How fast is the car going at the end of the braking period? (m/s) (b) How far has the car gone? (m) 2. A ball is hit with a paddle, causing it to travel straight...

Please help me
A San Francisco cable car is pulled by a cable running under the street. The cable moves at a constant speed of 9.50 mi/hr. The person who operates the cable car (called a gripman) operates a grip that grabs hold of the moving cable. (See Figure 2.) The gripman can allow the cable to slide through the grip so that the car can move at a speed that is slower than the cable. In Figure 2 the...
