Q. A 3.0 kg toy car can move along an x axis; Figure gives Fx of the force acting on the car, which begins at rest at time t=0. The scale on the Fx axis is set by Fxs = 4.0 N. In unit-vector notation, what is p at (a) t = 5.0 s and (b) t = 1.0 s, (c) what is v at t = 1.0 s?

Q. A baseball player hits a ball towards the outfield with an initial velocity of 76.0 m/s at an angle of 45 relative to the ground. The outfield is 118 m away and is 4.0 m tall.

Does the ball clear the fence for a homerun? (Determine the height when the ball is 118 m away)
