A baseball is hit at an angle 0 and travels along a parabolic arc before it strikes the ground. Which one of the following statements is true? O The acceleration of the ball decreases as the ball moves upward. O The velocity of the ball is O when the ball is at the highest point in the arc. O The acceleration of the ball is 0 when the ball is at the highest point in the arc. O The velocity of the ball is a maximum when the ball is at the highest point in the arc. O None of the above.
Particles A and B are traveling around a circular track at a speed of 8 m/sec at the instant shown. If thespeed of B is increasing by (at)B = 4 m/sec2, and at the same instant A has an increase in speed of (at)A =0.8 m/sec2, determine how long it takes for a collision to occur. What is the magnitude of the accelerationof each particle just before the collision occurs?
For a particle in plane curvilinear motion in a circle of constant radius, r, the direction of the component of acceleration, v²/r is: O Along a line tangent to the circle. O Outward from the center of the circle along the direction at an angle of 45° with the radius of the circle. O Along the radial direction away from the center of the circle. O Along the radial direction toward the center of the circle.
In the latest Indian Jones film, Indy is supposed to throw a grenade from his car, which is going 99.0 km/h , to his enemy's car, which is going 115 km/h . The enemy's car is 17.0 m in front of the Indy's when he lets go of the grenade. A If Indy throws the grenade so its initial velocity relative to him is at an angle of 45 ∘ above the horizontal, what should the magnitude of the initial velocity be? The cars are both traveling in the same direction on a level road. You can ignore air resistance. B Find the magnitude of the velocity relative to the earth.
VCM-2 As Khanh is driving her car along a straight road with a constant speed, she passes over a series of hills and dips. Each dip and hill has a radius of curvature of 250m She has a 5.00kg package sitting on a scale on the seat beside her. On one stretch of the road she passes thru a dip and then over a hill as shown below. a) Use the velocity vectors shown for V1 and V2, the velocities just before and just after the bottom of the dip, to show the direction of AV, the change in velocity in going thru the bottom of the dip. R=250m Car at the top of the hill. Car at the bottom of the dip. V2 b) Apply Fnet-ma to write symbolic equations for the package when it is in the car at the bottom of the dip. Include all forces on the package. If something equals zero, show it here, otherwise use no numbers in this step. R=250m

Mary is standing at the top of a hill admiring the view. The hill is at a 4.40° tilt. 30.0 m down the hill an old man lets go of a stroller with a baby inside it. The stroller starts to roll downhill with its frictionless wheels. Mary starts to run after it with her best acceleration of 1.90 m/s2. How far has the stroller rolled before she catches it?
