Use equation:

Fc= mv2r.

If Fc = 3.3, m = 97, and r = 6.40 x 106, what is v?

Use equation: Gm1m2d2=F. If F = 1.7 x 10-12, m1 = m2 = 8.0, and G = 6.67 x 10-11, what is d?

Use equation: Gm1m2d2=F. If F = 2.75x10-12, G = 6.67x10-11, d = 2.6, and m1 = 0.37, what is m2?

Use equation: m1v1+m2v2=m1v1'+m2v2'. If m1 = 0.035, m2 = 2.5, v1 = 475, v2 = 0, v1'= 275, what is v2'?

Use equation: W=Fd cosθ. If F = 805, W = 1.8x104,  = 32º, what is d?
