The total distance traveled by the body is the sum of the distance it traveled for the first five seconds which is 10 m and that of the next five seconds which is 30 meters. Thus, the total distance traveled is 40 m. Dividing this by the time, will give the average speed. The average speed is therefore, 4 m/s. The answer is letter C.

1. At which location does the pendulum have the least gravitational potential energy? Why?
Delicious77 [7]

Answer:Point B

Explanation:When it is at the bottom of its swing (arm straight up and down). When it is at its lowest point, Gravity can not pull it down any further. This position also has the most kinetic energy because after it passes the bottom, it goes back up again and loses speed. so when the pendulum is at the bottom it is traveling the fastest it will go.

The motor of a ski boat generates an average power of 2.74 × 10^4 W when the boat is moving at a constant speed of 14.3 m/s. Whe
Roman55 [17]

Answer:

T = 4517.48 N

Explanation:

It is given that,

Average power of the motor, P_1=2.74\times 10^4\ W

Speed of the boat, v_1=14.3\ m/s

Force or tension acting on the motor at this point is given by :

P=T\times v

T=\dfrac{P_1}{v_1}

T=\dfrac{2.74\times 10^4}{14.3}

T = 1916.08 N

Average power generated by the engine, P_2=9.2\times 10^4\ W

Force or tension acting on the motor at this point is given by :

P=T\times v

T=\dfrac{P_2}{v_2}

T=\dfrac{9.2\times 10^4}{14.3}

T = 6433.56 N

So, the tension in the tow rope that is pulling the skier is, T = 6433.56 N - 1916.08 N = 4517.48 N
