A basketball player is running at 4.70 m/s directly toward the basket when he jumps into the air to dunk the ball. He maintains his horizontal velocity. (For each answer, enter a number.) (a) What vertical velocity (in m/s) does he need to rise 0.850 meters above the floor? m/s (b) How far (in m) from the basket (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the basket? m
Consider the pendulum shown in the figure (Figure 1). Note that the pendulum's string is stopped by a peg when the bob swings to the left, but moves freely when the bob swings to the right. Is the period of this pendulum greater than, less than, or the same as the period of the same pendulum without the peg? (Choose 1) The period of this pendulum is greater than the period of the same pendulum without the peg. The period of this pendulum is less than the period of the same pendulum without the peg. The period of this pendulum is the same as the period of the same pendulum without the peg. Calculate the period of this pendulum in terms of L and l Evaluate your result for L = 1.0 m and l = 0.20 m
A certain airplane has a speed of 303.3 km/h and is diving at an angle of 0= 26.0° below the horizontal when the pilot releases a radar decoy (see the figure). The horizontal distance between the release point and the point where the decoy strikes the ground is d = 676 m. (a) How long is the decoy in the air? (b) How high was the release point? (a) Number i 8.9 Units S (b) Number i -716.6 Units m
A basketball player is running at 4.60 m/s directly toward the basket when he jumps into the air to dunk the ball. He maintains his horizontal velocity. (For each answer, enter a number.) (a) What vertical velocity (in m/s) does he need to rise 0.600 meters above the floor? m/s (b) How far (in m) from the basket (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the basket? m
During a recent winter storm, bales of hay had to be dropped from an airplane to a herd of cattle below. Assume the airplane flew horizontally at an altitude of 222 m. with a constant velocity of 44.0m / s and dropped one bale of hay every 3.0 seconds. It is reasonable to assume that air resistance will be negligible for this situation. About how far apart from each other will the bales land on the ground? Answer in m (rounded to the nearest whole number)
