Part C What is the magnitude of the acceleration? Express your answer in meters per second squared. a= V ΑΣΦ ? m/s²

A skateboarder travels on a horizontal surface with an initial velocity of 3.6 m/s toward the south and a constant acceleration of 2.5 m/s? toward the east. Let the z direction be eastward and the y direction be northward, and let the skateboarder be at the origin at t =0.

Please can you help me with questions 3 and 4?

A remote-controlled car is moving in a vacant parking lot. The velocity of the car as a function of time is given by = [5.00 m/s - (0.0180 m/s³)t²] i + [2.00 m/s + (0.550 m/s²)t]j. v = 7.00 Submit Previous Answers ✓ Correct Part D What is the direction (in degrees counterclockwise from +-axis) of the velocity of the car at t = 6.50 s? Express your answer in degrees. 0₂ = 52.7 ° Submit ✓ Part E a = Previous Answers Correct What is the magnitude of the acceleration of the car at t = 6.50 s?

A cat walks in a straight line, which we shall call the -axis, with the positive direction to the right. As an observant physicist, you make measurements of this cat's motion and construct a graph of the feline's velocity as a function of time (Figure 1). I. Calculate the area under the graph between t = 0 and t = 6.0 s. (Express your answer to two significant figures and include the appropriate units.) II. For the time interval t = 0 to t = 6.0 s, what is the magnitude of the average velocity of the cat? (Express your answer to two significant figures and include the appropriate units.) III. Use constant-acceleration equations to calculate the distance the cat travels in this time interval. (Express your answer to two significant figures and include the appropriate units.)

You're driving down the highway late one night at 20 m/s when a deer steps onto the road 35 m in front of you.
