The force shown in the attached figure is the net eastward force acting on a ball. the force starts rising at t = 0.012 s, falls back to zero at t = 0.062 s, and reaches a maximum force of 35 n at the peak. determine with an error no bigger than 25% (high or low) the magnitude of the impulse (in n-s) delivered to the ball. hint: do not use j = fδt. look at the figure. find the area of a nearly equally sized triangle.

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

Holes drilled several kilometers into earth’s crust provide direct evidence about earth’s interior in the form of

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.
