In 1874, a swarm of locusts descended on Nebraska. The swarm's mass was estimated to be 2.5 x 1010 kg. If this swarm were split in half and the halves
separated by 1.0 x 108 m, what would the magnitude of the gravitational force
between the halves be?

Ajogger accelerates from rest to 4.86 m/s in 2.43 s. a car accelerates from 20.6 to 32.7 m/s also in 2.43 s. (a) find the magnitude of the acceleration of the jogger. (b) determine the magnitude of the acceleration of the car. (c) how much further does the car travel than the jogger during the 2.43 s?

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.
