2. A person walks front at a constant amphetamine of 5.00 m/s along a straight transmission line from point A to point B and then back along the line from B to A at a constant speed of 3.00 m/s. What is (a) her average speed over the entire explode? (b) her average stop number over the entire trip?

3.A position-time graph for a particle moving along the x axis is shown in Figure P2.7. (a) Find the average velocity in the time interval t = 1.50 s to t = 4.00 s. (b) Determine the instantaneous velocity at t = 2.00 s by measuring the slope of the tangent line shown in the graph. (c) At what value of t is the velocity zero?

4..Find the instantaneous velocity of the particle described in Figure P2.3 at the following times: (a) t = 1.0 s, (b) t = 3.0 s, (c) t = 4.5 s, and (d) t = 7.5 s.

5.A particle starts from rest and accelerates as shown in Figure P2.12. Determine (a) the particles speed at t = 10.0 s and at t = 20.0 s, and (b) the distance traveled in the first 20.0 s.

6.An object moves along the x axis according to the equation x(t) = (3.00t2 2.00t + 3.00) m. Determine (a) the average speed betwixt t = 2.00 s and t = 3.00 s, (b) the instantaneous speed at t = 2.00 s and at t = 3.00 s, (c) the average quickening between t = 2.00 s and t = 3.00 s, and (d) the instantaneous speedup at t = 2.00 s and t = 3.00 s.

7.An object moving with uniform acceleration has a velocity of 12.0 cm/s in the positive x direction when its x order is 3.00 cm. If its x coordinate 2.00 s later is 5.00 cm, what is its acceleration?

8.A jet plane lands with a speed of 100 m/s and can accelerate at a uttermost rate of 5.00 m/s2 as...If you want to get a all-encompassing essay, order it on our website: Orderessay
