The ball's velocity at time is
where is the acceleration due to gravity. So after 1.5 seconds, the ball's velocity is
so the ball's speed after 1.5 seconds is also 49.5 m/s.
quantitative means how much there is like how many.
Explanation:
It is given that,
Initial speed of a golfer, u = 29 m/s
If it travels the maximum possible distance before landing. It means that it is projected at an angle of 45 degrees.
(a) We need to find the time spent by the ball in the air. It can be calculated by using second equation of motion.
Here,
a = -g
s = 0 (it is displacement and it is equal to 0 as the ball lands on the green).
So,
So, it will take 4.184 seconds in the air.
(b) let x is the longest hole in one that the golfer can make if the ball does not roll when it hits the green. It can be given by :
Hence, this is the required solution.

Answer:
(a) reaction at each front wheel is 5272N (upward)
(b) force between boulder and pallet is 4124N (compression)
Acceleration of the truck = 1 m/ (to the left)
when the truck moves 1 m to the left, the boulder is B and pallet A are raised 0.5 m, then,
= 0.5 m/ (upward) , = 0.5 m/ (upward)
Let T be tension in the cable
pallet and boulder: ∑fy = ∑(fy)eff = 2T- ( + )g = ( + )
= 2T- (400 + 50)*(9.81 m/) = (400 + 50)*(0.5 m/)
T = 2320N
Truck: = ∑()eff: = (3.4m) + (2.0m) - T (0.6m)= (1.0m)
Nf = (2.0m)(2000 kg)(9.81 m/ )/3.4m - (0.6 m)(2320 N)/3.4m + (1.0 m)(2000 kg)(1.0 m/) = 11541.2N - 409.4N - 588.2N = 10544N
∑fy (upward) = ∑(fy)eff: + - g = 0
10544 + - (2000kg)(9.81 m/ ) = 0
= 9076N
∑fx (to the left) = ∑(fx)eff: - T =
= 2320N + (2000kg)(9.81 m/ ) = 4320N
(a) reaction at each front wheel:
1/2 (upward): 1/2 (10544N) = 5272N (upward)
(b) force between boulder and pallet:
∑fy (upward) = ∑(fy)eff: + g -
= (400kg)(9.81 m/) + (400kg)(0.5 m/) = 4124N (compression)
