Plz help i will give 1. A popular sprinter of mass 60 kg, was running a 100 m race. Her velocity was measured over a 10.0 s period. The results are recorded in Table 1.

Velocity, v/ms^-1 0.0 2.5 5.0 7.5 10.0 10.0

Time, t/s 0.0 2.0 4.0 6.0 8.0 10.0

a. Use the results from Table 1 to plot a graph of Velocity versus Time on a graph paper.
b. Determine the slope of the graph over the first 6.0 s of the race.
c. What quantity does the slope of the graph represent?

To protect all four receptacles on a branch circuit that surrounds a swimming pool, you would install which of the following configurations? a. gfci feed-through receptacle at the end of the load's circuit b. gfci-terminated receptacle at the beginning of the load's circuit c. gfci feed-through receptacle at the beginning of the load's circuit and the other receptacles connected to the load side of that receptacle d. gfci-terminated receptacle at each end of the load's circuit

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?
