3.30 m and a top speed of 4.90 m/s. Suppose a mongoose and a black mamba find themselves nose to nose. In an effort to escape, the snake accelerates past the mongoose at 7.82 m/s2 from rest. How much time ?top does it take the snake to reach its top speed? How far ?snake does the snake travel in that time? How much time ?react does the mongoose have to react before the black mamba's tail passes the mongoose's nose?

A soccer ball is released from rest at the top of a grassy incline. After 8.3 seconds, the ball travels 50 meters and 1.0 s after this, the ball reaches the bottom of the incline.What was the magnitude of the ball's acceleration, assume it to be constant? How long was the incline?

a) how long does it take for you to reach the open door and jump in? b) what is the maximum time you can wait before starting to run and still catch the bus

A woman backs her van out of her parking space with a constant acceleration of 1.8 m/s2. Assume that her initial motion is in the positive direction. Part A: How long does it take her to reach a speed of 2.1 m/s in seconds?  Part B: If she then brakes to a stop in 0.65 s, what is her acceleration in meters per square second?

A truck starts from rest. It accelerates for 10 s at 5.0 m/s2. Then it immediately decelerates for 2.0 s at -10 m/s2. How far does it travel, in meters?

An aircraft starts at rest and is accelerated at 10 m/s2 for 30 seconds, at which time the aircraft becomes airborne. What is the distance traveled during the 30 seconds? Assume the acceleration is constant.

A ball is dropped in a stationary elevator and hits the floor in 0.65 s. How long does it take for the ball to hit the floor if the elevator is moving down with a constant speed of 3.0 m/s. Consider g = 9.8 m/s². Select one: O a. 1.16 s O b. 1.02 s O c. 0.76 s O d. 0.84 s

QUESTION 2 Which of the following is an accurate statement? O A. It is possible to add a scalar quantity to a vector. O B. Even though two vectors have unequal magnitudes, it is possible that their vector sum is zero. OC. Rotating a vector about an axis passing through the tip of the vector does not change the vector. OD. The magnitude of a vector is independent of the coordinate system used. O E. The magnitude of a vector can be zero even though one of its components is not zero.

A train, traveling at a constant speed of 22.0 m/s, comes to an incline with a constant slope. While going up the incline, the train slows down with a constant acceleration of magnitude 1.40 m/s². 1. What is the speed of the train after 7.40 s on the incline? 2.How far has the train traveled up the incline after 7.40 s?

a car travels on a straight, level road. a) Starting from rest, the car is going 42 ft/s (29 mi/h) at the end of 4.5 s. What is the car's average acceleration in ft/s2? b) In 3.5 more seconds, the car is going 84 ft/s (57 mi/h). What is the car's average acceleration for this time period? (c) The car then slows to 63 ft/s (43 mi/h) in 2.5 s. What is the average acceleration for this time period? (d) What is the overall average acceleration for the total time?
