BackA basketball is thrown along a curved path with an initial speed of and remains in the air for . Assuming the horizontal component of velocity is and neglecting air resistance, how far horizontally will the basketball travel before hitting the ground?
When a toy car coasts along a curved track at constant speed, which of the following statements about the net force acting on the car is correct?
In the context of motion along curved paths, how can the motion of particles that make up an object be represented in a still image?
A car of mass starts from rest at the top of a frictionless dip of height . What is the car's speed at the bottom of the dip?
The movement from point to point along a curved path is best described as which of the following?
When a skydiver opens their parachute while descending, how does their change immediately after the parachute deploys?
A ball is attached to a horizontal cord of length ℓ whose other end is fixed, Fig. 8–45. If the ball is released, what will be its speed at the lowest point of its path?
A ball is attached to a horizontal cord of length ℓ whose other end is fixed, Fig. 8–45. A peg is located a distance h directly below the point of attachment of the cord. If h = 0.80ℓ, what will be the speed of the ball when it reaches the top of its circular path about the peg?
The small mass m sliding without friction along the looped track shown in Fig. 8–47 is to remain on the track at all times, even at the very top of the loop of radius r. In terms of the given quantities, determine the minimum release height h.
The small mass m sliding without friction along the looped track shown in Fig. 8–47 is to remain on the track at all times, even at the very top of the loop of radius r. If the actual release height is 2h, calculate the normal force exerted by the track at the bottom of the loop.
The small mass m sliding without friction along the looped track shown in Fig. 8–47 is to remain on the track at all times, even at the very top of the loop of radius r. (c) by the track at the top of the loop, and (d) by the track after the block exits the loop onto the flat section.
