Solution: (a) ”Remains in the air” means the total flight time. To find this time put the coordinate of the impact of the projectile into the y= −1 2 gt 2 + v 0tsinα + y 0 and then solve for the time t tot. Let the origin of the coordinates be the firing point. Therefore, the projectile hits the ground −45 mbelow the origin! y= − 1 2 ...
Some key terms to know, and how to calculate them, are: Time of flight: how long the projectile is in the air. Maximum height attained: the height at which the projectile is momentarily at rest. Range: the horizontal distance travelled by the projectile. How to find the time of flight, maximum height and range.
Of course, we also need to specify the time interval used in our discretization of the motion, we'll call it delta_t as usual. Since we're interested in both velocity and position of the projectile as functions of time, we'll construct a spreadsheet with five columns: time, v_x, v_y, x, y.
Phys 191 – Uncertainty Worksheet. Convert the following to relative uncertainties: 2.70 ± 0.05 cm. 12.02 ± 0.08 cm. Convert the following to absolute uncertainties: 3.5 cm ± 10 % b. 16 s ± 8 %. Complete the following, determining the appropriate uncertainty: (2.70 ± 0.05 cm) + (12.02 ± 0.08 cm)
golfer drives her golf ball from the tee down the fairway in a high arcing shot. When the ball is at the highest point of its flight: the velocity and acceleration are both zero. the x-velocity is zero and the y-velocity is zero.
PROJECTILE MOTION WORKSHEET. 1. A stone is thrown horizontally at 8.0 m/s from a cliff 80m high. How far from the base of the cliff will the stone strike the ground? 2. A toy car moves off the edge of a table that is 1.25m high.
24 cze 2024 · You may calculate the time of flight of a projectile using the formula: t = 2 × V₀ × sin(α) / g. where: t – Time of flight; V₀ – Initial velocity; α – Angle of launch; and; g – Gravitational acceleration.
