A small block has constant acceleration as it slides down a frictionless incline. The block is released from rest at the top of the incline, and its speed after it has traveled 6.00 mm to the bottom of the incline is 3.80 m/sm/s.
A).
What is the speed of the block when it is 4.60 mm from the top of the incline?
Express your answer with the appropriate units.
The velocity of a particle is given by v = 23t2 - 110t + 52, where v is in meters per second and t is in seconds. Plot the velocity v and
acceleration a versus time for the first 6.4 seconds of motion and evaluate the velocity when a is zero. Make the plots and then
answer the questions.

The position of a toy car driving on a horizontal surface is given by x = 4.0m - (2.0m/s)*t + (1.5m/s^2 )*t^2 .
a. Determine the position of the car at t=1.0s, 2.0s, and 3.0s.
b. What is the average velocity over the time interval t=1.0s to t=3.0s?
c. What is the instantaneous velocity at t=2.0s?
d. Draw graphs each for the position (x) function versus time, velocity versus time, and acceleration versus time. Hand drawn-graphs are encouraged (for practice for the midterm), though computer generated is allowed as well. Make sure to be very specific in the details (labels, scales, units, where the intercepts are, etc.).

During one heat of a swim meet, a swimmer performs the crawl stroke in a pool 50.0 mm long, as shown in (Figure 1). She swims a length at racing speed, taking 24.0 ss to cover the length of the pool. She then takes twice that time to swim casually back to her starting point. Find (a) her average velocity for each length and (b) her average velocity for the entire swim. c) If the swimmer could cross a 15 kmkm channel maintaining the same average velocity as for the first 50 mm in the pool, how long would it take?arrow_forwardThe acceleration of a particle is given by a = 2t - 15, where a is in meters per second squared and t is in seconds.
