Weegy: mass= 120 kilograms ;velocity = 30 m/s p = m*v = 120*30 = 3,600 kg-m/s The momentum is 3,600 kg-m/s. p = mv p = 120*30 p = 3,600 (More)

Weegy: 120 N is required to accelerate a body with a mass of 15 kilograms at a rate of 8m/s. Solution: F=ma m=15 a=8m/s/s f=15*8=120N (More)

Weegy: If an object has a mass of 20 kg, The force of gravity acting on earth is 196N force =mass *acc , force = 20 *9.8 = 196N (More)

Weegy: p = mv p = 5 kg* 2 m/s p = 10 kg ms/s Thus, the momentum is 10 kg m/s. (More)

Weegy: The force of gravity acting on a child's mass on earth is 490 newtons. The child's mass is 50kg. Solution: Force = mass x acceleration; Child's mass = f/a = 490/ 9.8 = 50kg. (More)
