Answer:
1.25 s
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 25 m/s
Angle of projection (θ) = 30°
Acceleration due to gravity (g) = 10 m/s²
Time (t) to reach highest point =?
The time taken for the particle to reach the highest point can be obtained as follow:
t = uSineθ / g
t = 25 × Sine 30 / 10
t = 25 × 0.5 / 10
t = 12.5 / 10
t = 1.25 s
Thus, it will take the particle 1.25 s to reach the highest point.
