1 a A rectangular block of metal of density 8000 kg/m3 measures 2 cm by 3 cm by 10 cm. What is the mass of the block?
A 48 g
B 0.48 kg
C 4.8 kg
D 48 kg

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

Asap i'm in class rn a 1,000-kg car is traveling 20 m/s on a flat stretch of road. it gets to a hill and coasts uphill until it stops. how high up the hill does the car travel? givens: equation: 1/2mv2initial=mghfinal solve for h. plug & chug, label.

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?
