A72 kg sled is pulled forward from rest by a snowmobile and accelerates at 2.0m/s^2( forward) for 5.0 seconds. the force of friction acting on sled is 120 n (backwards). the total mass of a snowmobile and driver is 450 kg. the drag force acting on snowmobile is 540 n (backwards). determine the tension in the rope and the force exerted by the snowmobile that pushes the sled forward.

1.)the isotope cobalt-60 has a nuclear mass of 59.933820 u calculate the mass defect of cobalt-60 using the following information. mass of proton: 1.007825 u mass of neutron: 1.008665 u 1 u = 931.5 mev 2.)the isotope cobalt-60 has a nuclear mass of 59.933820 u calculate the binding energy of cobalt-60 using the following information. mass of proton: 1.007825 u mass of neutron: 1.008665 u 1 u = 931.5 mev 3.)the isotope cobalt-60 has a nuclear mass of 59.933820 u calculate the binding energy per nucleon of cobalt-60 using the following information. mass of proton: 1.007825 u mass of neutron: 1.008665 u 1 u = 931.5 mev

Acar travels in reverse. it covers 150 meters in 12 seconds what is the velocity of the car what is the speed of the car
