A crate slides along the x-axis and the figure below shows a record of its velocity as a function of time. Every gridline along the vertical axis corresponds to 2.00 m/s and each gridline along the horizontal axis corresponds to 1.50 s. (Enter your answers in m/s². Indicate the direction with the signs of your answers. Note that t = 0 at the intersection of the axes.) v (m/s) S V t(s) (a) Determine the average acceleration of the crate in the time interval t = 0 to t = 7.50 s. m/s² (b) Determine the average acceleration of the crate in the time interval t = 7.50 s to t= 22.5 s. m/s² (c) Determine the average acceleration of the crate in the time interval t = 0 to t = 30.0 s. m/s²

Express your answer in meters per second squared to two significant figures. a=_____________m/s2

A car is traveling with a constant speed along a road that has a form of a square. The car starts at the beginning of one side of the square and covers two and a half sides. The speed of the car is 50 miles/hour. What is its average velocity ?   plz also show step by step on how you acquired the formula you are using to solve this problem. Thank You!!!!

Shown below is a graph of velocity versus time for a moving object. The object starts at position x = 0. What is the final position in meters, from t = 0 seconds to t= 3 seconds? Represent your answer with 3 significant figures. (No unit is needed in your answer, it is already given in the question statement.)

Two vehicles start out traveling side by side along a straight road. Their position functions, shown in the following graph, are given by s = f(t) and s = g(t) , where s is measured in meters and t is measured in seconds. 10+ 7- 4 s=ft) s= g(t) Which vehicle has traveled farther at t = 2 seconds? Vehicle f Vehicle g What is the approximate velocity of the f vehicle at t = 3 seconds? meters per second What is the approximate velocity of the g vehicle at t = 3 seconds? meters per second Which vehicle is traveling faster at t = 4 seconds? Vehicle f O Vehicle g

A ball is thrown straight upward, and it reaches a maximum height of 2.80 seconds.   b). What is the maximum height reached by the ball shown in a formula showing what the variables are defined as in a diagram?

t (seconds) 0 4 8 12 16 Velocity (ft/sec) 0 4 10 16 24   Shown in the table is the velocity of a car at varying times. Use this data to sketch a smooth curve relating the two variables. Draw rectangles on this graph to help you underestimate the total distance traveled by the car during the first 16 seconds. What underestimate did you obtain? _______________________feet   Draw rectangles on this graph to help you overestimate the total distance traveled by the car during the first 16 seconds. What overestimate did you obtain?   ______________________ feet

Calculate the height of a cliff if it takes 2.35 s for a rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.00 m/s. What is the maximum height reached by the rock? How long would it take to reach the ground if it is thrown straight down with the same initial speed? Clearly state the formulae you’re using and what your letters/symbols mean.
