2. ### *Physics Question* A block of mass m = 0.794 kg is fastened to an unstrained horizontal spring whose spring constant is k = 80.2 N/m.?

By Hooke's Law, F = -kx = -80.2N/m * 0.130m = -10.4 N The sign indicates "toward the -x axis." If you find this helpful, please award Best Answer!

3. ### A 0.52kg object vibrates at the end of a horizontal spring (k = 15N/m). When the object’s kinetic energy is 7.3J, what is its speed?

TMI. To find the speed, v, all you need are the mass, M, and the kinetic energy, T, because: T = ½Mv² So just solve that for v, and then plug in the values for M and T.

4. ### A car travels up a hill at a constant speed of 41 km/h and returns down the hill at a constant speed of 62 k?

you need to find the time spent at each speed say the hill is 10 km long 10 / 41 = 0.2439 time up hill 10 / 62 = 0.1613 time down hill 0.2439 + 0.1613 = 0.4052 total time 0.2439 / 0.4052 = 0.6019 %age of time spent going up hill 0.1613 / 0.4052 = 0.3981 %age of time spent going down hill 41 X 0.6019 = 24.6779 62...

10. ### A circular field of 1 km diameter has 5 meter walking track around it. (Width of walking track included in 1 k?

circumference = 2 pi r = 2 x 3.142 x 0.5km = 3.142 km = 3142m total area = 3142 x5 = 15708 m^2 9 square feet = 1 sq yard so 9 x area in m^2 = 141371 cost in rupees = area in square feet so answer A is closest to this.
