Question

Projectile Path Pointsi l An astronaut on planet X observes and plots the position of a projectile at constant time intervals of 0.528 s. (1) Calculate the horizontal speed of the ball. (2) Calculate ay, the vertical acceleration due to gravity on Planet X. The planet has no atmosphere NOTE: Both answers must be correct to get credit. 105 100 80 75 70 65 60 35 30 25 20 10 51615 20 25 30 35 40 45 5 5560 65 70 Horizontal position, x. (n) 80 20 The horizontal speed is constant. Use a large time interval to calculate its value. 7 8m/s/s A positive vertical acceleration would corresponds to increasing speed along the vertical-axis. You may need to take multiple readings of your positions on the graph and then average them to obtain the correct answer. Sutmit Arawer Incorrect. Tries 1/10Previous Tries

Explanation / Answer

(1) Taking, say, last point in the graph, which shows 62.5m as the horizontal poition at time t= 0.528*9= 4.752s; the horizontal velocity is then v = 62.5/ 4.752= 13.15 m/s

(2) acceleration = change in velocity/ time taken.

Between 2nd and 3rd point, v= 58-34/ 0.528= 45.45m/s

Between 4th and 5th point, v=91-77/ 0.528 = 26.51m/s

So, a= change in velocity/ time taken = 26.51-45.45/ 2*0.528= -17.93 m/s^2
