Explanation:
It is given that,
Initial velocity of frog, u = 100 m/s
It jumps at an angle of 60 degrees.
(a) Let 
are the x and y components of velocity. It can be calculated as :
(b) Let y is the maximum height reached by the frog. It can be calculated using the third equation of motion as :
At maximum height, 
and a = -g
y = 382.63 meters
(c) Let t is the time taken by the frog to reach its maximum height. It can be calculated as :
t = 8.83 seconds
Hence, this is the required solution.
Instantaneous acceleration is defined as rate of change in velocity
it is given by the equation
so here it shows that acceleration is always depends on change in velocity with time and now if we required this change in velocity with time for a small instant of time then it will be given by the slope of velocity and time graph.
So here the graph must be like this to find the slope of any graph we always use the concept that for any graph between y and x we use
if we compare it with the formula of acceleration above
then on Y axis we must have to draw the speed and on x axis we must have to draw the time
so correct answer must be
<u> d) Place time on the x-axis and velocity on the y-axis</u>
Squeezing the clutch lever to slow down is best to be done when approaching a curve and is denoted as option C.
<h3>What is Clutch?</h3>
This is a mechanical device which used in the engagement and disengagement of transmission system in a vehicle.
Slowing down will give the driver more time to maneuver the curves so as to prevent accident. This is why it is imperative to squeeze the clutch in such road condition.

7500J
Explanation:
Given parameters:
Weight of child = 150N
Height of lifting = 50m
Distance = 50m
Unknown:
Work done by the woman = ?
Solution:
Work done by a body is the force applied to move a body through a given distance.
Work done = Force x distance
Weight is a force impacted by the mass of a body and the gravity on it.
input the parameters:
Work done = 150 x 50 = 7500J
