What is the distance fallen after 4 s for a freely falling object starting from rest ? Use g = 9.8 m/s2. State your final answer in a numerical form, up to the first decimal place, with appropriate units in an abbreviated form.
A ball is thrown from a rooftop with an initial downward velocity of magnitude v0 = 1.1 m/s. The rooftop is a distance above the ground, h = 46 m. In this problem use a coordinate system in which upwards is positive. Part (a) Find the vertical component of the velocity, Vfy, in meters per second, with which the ball hits the ground. Part (b) If we wanted the ball's final speed to be exactly 27.3 m/s from what height, hnew (in...

-1 A 10 g marble rolls to the left with a velocity of 0.4 m.s and makes a head-on collision with a 30 g marble rolling to the right with a velocity of 0.2 m.s The final velocity of the larger (30 g) marble after the collision is 0.15 ms to the right. 0.200 m/s 0.400 m/s 30.0 g 10.0 g m.s A. What is the final velocity of the small marble? B. What type of collision is this?
A train has a final velocity of 110km/h. it accelerated for 36s at 0.50 m/s what was its initial velocity
A vehicle has initial velocity of V。= 31 m/s and driver sees a fallen tree 81 m in front of the car. The car has an acceleration a = 6.1 m/s2 and the perception-reaction time of the driver is 0.75 s.Calculate the velocity of the vehicle when it hits the tree.
What are the magnitude Av and angle of the change in velocity if the initial velocity is 65.0 m/s south and the final velocity is 35.0 m/s west? Let the angle ê be measured relative to the east direction (e.g., 0 = 90° means Ay points north, 0 = 180° means Au points west, etc.). AU m/s =
Determine the magnitude and direction of the change in velocity if the initial velocity is 26 m/s south and the final velocity is 35 m/s west. the magnitude of the change in velocity equals 44 m/s What is the direction of the change in velocity? units are north of east
A 10.0-g marble slides to the left with a velocity of magnitude 0.400 m/s on the frictionless, horizontal surface of an icy New York sidewalk and has a head-on, elastic collision with a larger 30.0-g marble sliding to the right with a velocity of magnitude 0.200 m/s. Let +x be to the right. (Since the collision is head-on, all the motion is along a line.) (Figure 1) Figure1 of 1 Part A Find the magnitude of the velocity of 30.0-g...
