Answer:
255 m
Explanation:
The car is moving by uniform motion (constant velocity), so we can calculate the distance it travels by using the equation
where
d is the distance travelled
v is the velocity of the car
t is the time interval
In this problem:
v = 7.5 m/s is the velocity of the car
t = 34 s is the time interval
Therefore, the distance covered by the car is
Answer:
u = 104.68 m/s
Explanation:
given,
horizontal distance = 150 m
elevation of 12.4 m
angle = 8.6°
horizontal motion = x = u cos θ. t .............(1)
vertical motion =
................(2)
from equation(1) and (2)
..........{3}
u = 104.68 m/s
The initial speed of the ball is u = 104.68 m/s
