- The initial velocity of a car is 35 m/s due North. Its final velocity is 42 m/s at 15 degrees South of East. If this takes 30 seconds, what is the magnitude and direction of the car's average acceleration?Answers should be in 3 decimal places. A particle moving in a straight line has an acceleration a = 4t – 9. Its initial velocity is 4m/s. Find the velocity (in m/s) after 6s.A school bus traveling along at 12.6km/h slows to 4.32km/h in 2.50s. How far did it travel (in m)?
- A cheetah can accelerate from rest to a speed of 30.0 m/s in 7.00 s. What is its average acceleration i meters per second squared?An arrow is shot vertically upward and then 1.87 s later passes the top of a tree 37.0 m high. How much longer will the arrow travel upward, and how high will it go? time heightA marching band player walks directly north at a speed of 2.50 m/s for a time of 12.0seconds, turns 35.00to the east and walks at half that speed for another 15.0 seconds.What is the players total displacement and average velocity for the entire trip?
- A bullet is fired through a board, 0.28 cm thick, with its line of motion perpendicular to the face of the board. If it enters with a speed of 50 m/s and emerges with a speed of 15 m/s, what is the bullet's acceleration in m/s as itYou get in your car and drive north, accelerating up to 60mph. Draw your velocity vector and acceleration vector some time during your acceleration. How would these change if you encountered traffic and started to brake?
