- A bullet shot from a rifle has mass of 10.0 g and travels to the right at 350 m/s. It strikes a target, a large bag of sand, penetrating it a distance of 34.0 cm. Find the magnitude and direction of the retarding force that slows and stops the bullet.A drone is being directed across a frictionless ice- covered lake. The mass of the drone is 1.50 kg, and its velocity is 3.00i m/s . After 10.0 s, the velocity is 9.00i+4.00j m/s . If a constant force in the horizontal direction is causing this change in motion, find (a) the components of the force and (b) the magnitude of the force.When serving a tennis ball, the player hits it when its velocity is zero (at the highest point of a vertical toss). The racket exerts a force of 520 N on the ball for 5.00 ms, giving it a final velocity of 46.0 m/s. Using these data, find the mass (in g) of the ball. g
