Một chất điểm đang di chuyển trên đường cong y = x − (x 2/400), trong đó x và y tính theo f t.

Nếu thành phần vận tốc theo phương x không đổi là vx = 2(f t/s), xác định độ lớn của vận tốc và gia tốc

chất điểm khi x = 20(f t)

Suppose that two objects attract each other with a gravitational force of 16 units. if the distance between the two objects is double, what is the new force of attraction between the two objects?

Shari uses the data in the table to predict how her weight on venus would compare with her weight on earth. which is the best prediction shari could make? her weight is greater on venus because venus has less mass. her weight is lower on venus because the acceleration due to gravity is lower. her weight is lower on earth because it is farther from the sun. her weight is greater on venus because venus has a smaller diameter.
