Question

a grasshopper can jump a maximum horizontal distance of 20cm.If it spends negligible time on ground . calculate how far it can go along the road in 10 seconds take. g=10m/s^2​

Answer 1

Answer:

Explanation:

Range of a projectile is given by u2sin2θ /g

range will be maximum when

θ

=

45

So putting value of

θ

in the expression we get

U=√2

So it can travel along the ground with speed

Ucosθ=√2×1/√2=1m/s

d=vt

1×10 =10m

this may be the answer plzz verify..
